Waves Presentation

Transcript: Visible Light 700 nm - 400 nm Only electromagnetic waves we can see, we see these waves as the colors of the rainbow Each color has a different wavelength Ex: Colors, Light Bulbs Frequency Radio 30 kHz - 3 GHz Longest wavelengths in the electromagnetic spectrum Carry signals Ex: Telescope, radio stations Infrared lies between the visible and microwave portions of the electromagnetic spectrum Has a range of wavelengths Far infrared waves are thermal Ex: Remote, Infrared lamps Frequency- Number of waves made per cycle. Measured in Hertz. Relationship: Increasing frequency increases wavelength. Absorption Photons from light hit atoms and molecules causing them to vibrate Darker objects absorb more light Diffraction Bending & spreading of waves around an obstacle Most pronounced when light wave strikes an object with a size comparable with its own wavelength Refraction When light waves change direction as they pass from one medium to another Different wavelengths of light are slowed at different rates Change in speed bends light Gamma 200 kev - mev Most energy of any other wave in the electromagnetic spectrum Generated by radioactive atoms and in nuclear explosions Can kill living cells Ex: Sterilizing medical equipment, CT scans Micro 300 MHz - 300 GHz Good for transmitting information from one place to another Ex: satellite, microwave at home Waves Presentation Electromagnetic Waves Waves A wave is a disturbance that transfers energy through a medium from one point to another. Two types of waves are Transverse and Longitudinal. The energy of a wave is carried through solids, liquids, or gases. A medium is the substance that transports the wave from its source to another location. Longitudinal Waves' displacement is parallel to the direction of the wave and Transverse waves are perpendicular to the direction of the wave. Crest- Highest point of a wave. Trough- Lowest point of a wave. Positive Amplitude- Amplitude above the medium. Negative Amplitude- Amplitude below the medium. Wavelength- Distance between one crest or trough of a wave to the next. Waves that do not require a medium to propagate. Can travel not only through air and solid materials, but also through the vacuum of space. Electromagnetic Spectrum - the range of wavelengths or frequencies over which electromagnetic radiation extends. X-rays 100 ev - 200 ev Higher energy than ultraviolet waves Small wavelengths X-ray light tends to act more like a particle than a wave Ex: x-rays, Ultraviolet 400 nm - 10 nm These waves are invisible to the human eye 3 Regions: the near ultraviolet, the far ultraviolet, and the extreme ultraviolet Ex: Sun rays, Tanning bed Behavior of Waves Terms Reflection When light hits an object and bounces off Smoother surfaces reflect more Color is waves of light reflected Behavior of Waves Scatter When light bounces off an object in a variety of directions Amount of scattering depends on the wavelength, size, and structure of object Electromagnetic Waves Electromagnetic Waves

Multiple Background Images

Transcript: The last background image will be the bottom layer. Beware of trying to cram in too many overlapping images. All of the normal background image properties apply, they are just separated by commas. Background Properties background-image: url(image1.png), url(image2.jpg); background-size: 25%, cover; background-repeat: no-repeat, no-repeat; background-position: 50% 75%, center; Layered Images Here image1 will be on the top layer, while image3 will be the bottom layer. Remember, transparencies are only supported with certain image formats. You can overlay as many background images as you want, but remember that backgrounds affect visibility of site content. Background images can add variety and help make your page stand out. For example, in this presentation, the flying origami birds are the background image. Sometimes one background image isn't enough. Fortunately, CSS allows us to layer multiple background images. The first background image listed will be the first layer, followed by the second, etc. Below is a basic example of layered background images. Adding Multiple Backgrounds div { background: url(image1.png), url(image2.png), url(image3.png); } Multiple Background Images Adding multiple backgrounds is easy. Just add the next image in the same way you would a background image, separated by a comma. Multiple Background Images Be careful not to put opaque images on top or you won't see the the other layers. div { background: url(image1.png), url(image2.png), url(image3.png); } Sample Page For example:

Transcript: DVDs & Waves CONCLUSION A sonogram is a noninvasive medical procedure that helps diagnose and treat health conditions. The method uses high frequency sound waves to produce a specific image of the patient's body. They don't use radiation, so it's much safer than an x-ray since patients don't have to worry about the possible side effects of radiation exposure. (Two Views LLC) General Info! Compact Disk The CD was invented by James Russel in 1965 An audio CD or a CD-ROM has information coded in tiny pits on its surface. A laser light is focused to get information on the sequence of those pits. The Blue Ray disc was invented by the Blu-Ray disc association Its name was derived from the underlying technology, which uses a blue-violet laser to read and write data. Its correct abbreviation is BD, not BR or BRD! The spelling is NOT a mistake! In "Blu-ray" the letter 'e' was purposefully dropped so that the term could be registered as a trademark. There isn't any possible way to actually prevent a tsunami from happening. However, there are many ways to prepare for one in areas where tsunamis are active. With an effective warning system, people can be evacuated, and damage can also be prevented. Tsunami walls, flood gates, & channels are three common ways that tsunamis are potentially prevented. CD, DVD, & Blu-Ray Technology Credit Cards Driver's Licenses Used on some barcodes to prevent things from getting stolen the medical field (X-ray holography, Endoscopic holography, Etc.) Waves How to Prevent Tsunamis Caused when the ocean is suddenly displaced on a large scale by an underwater disturbance (earthquakes); the ocean floor is raised or dropped & large tsunami waves can be formed Holograms Sonograms Seismic Waves & Tsunamis Where is holography used? General Info! General Info! Digital Versatile Disc Invented in 1995 by Phillips, Sony, Toshiba & Time Warner. Storage Capacity from 4.7 GB to 17 GB Access rates differs from 600 KB/s to 1.3 MB/s Kenzie Peacock, Cheyenne Kovacsy, & Amy Figurski - 3rd period (CD) As the disc spins, the ray of radiation passes over tiny differences in elevation, which alters the the wavelengths of the reflected waves. These waves pass back through the system of lenses, which are refracted in a different direction and in turn alter an electrical current that is "read" to produce sound. Additionally, CD players use infrared light, which means the spaces on the CD must be far apart enough to allow for infrared's relatively large wavelength. DVD players go more in-depth on this concept by relying on visible red light, which has a shorter wavelength than infrared. Blu-Ray Discs use blue visible light, which have an even shorter wavelength. Principles of holograms: interference & diffraction of light waves Described as a "window with memory" Waves are used in many different ways, and are often a big part of our daily lives. Most of the time, we don't even realize they're being used! CD's, DVD's, Blu-Ray disks, holograms, seismic waves, tsunamis, and sonograms are just a few examples out of the abundance that exist! How do DVDs, Blu-Ray disks & CDs use waves?? Sonography can be used to examine the: uterus, ovaries, liver, kidneys, spleen, thyroid, pancreas, gallbladder and bladder. It is useful for seeing the inside of the heart to determine any blockages or abnormal structures, measuring blood flow, detecting kidney stones and identifying cancers early. It can also be used to guide other slightly invasive procedures with limited visibility like a needle biopsy or needle aspirations. (Sanford-Brown)

Presentation of images

Transcript: Presentation Of Images By: Imaan Henry Date 1 Concrete Exit This image is very bland. With a concrete floor leading to an exit. The exit playing as the vocal point. This image makes me feel as though some people don't have a choice on something and they are directed directly to one option. Like there is only one option on something and no where else to go. There's line and the image is parallel. Concrete Exit Line Of Treadmills Line Of Treadmills This image represents line of the treadmills and pattern because there are multiple treadmills behind each other creating pattern. The main vocal point is the middle treadmill and the empty hallway in the background gives more personality to the photo. I made it so the triangle aspect fit with the light, (which was artificial and natural light). I think all the elements in this image creates contrast. Painting Of Satisfaction Painting Of Satisfaction This image is really satisfying to look at. The reason is that the painting I took a picture of was really bright and included line, color, conjunction, harmony and value. The image felt unique because while the painting (which is the vocal point) is colorful and at the center, everything else felt bland and convenience store vibe. But the painting brightened everything up standing out from the background. I did not touch the painting respecting the work of the school and school guidelines. Morning sunlight Morning Sunlight This is one of the best images I've taken. I really like the type of lighting it has. It feels very warm and welcoming. It has line, color and harmony. It follows the school guidelines. One of the reasons why I liked it very much was the great usage of the triangle aspect. The composition guidelines I used to facilitate my good work was acknowledging the design elements and too keep a good aperture and shutter speed to maintain an excellent ISO. Parallel hallway Parallel Hallway I am really proud of this image. It is one of my most liked images. It has line space, color and contrast. The triangle aspect is fits really well into this photo. I think that because the aperture, shutter and ISO all fit together creating a good image. My main area of difficulty was the students in the hallway. I wanted toe photo to follow the school guidelines but also when humans are in photos they become the main vocal point. I also just prefer my photos with no people in them. This was difficult because when I waited for the students to pass these boys were still there. I got frustrated and still took the picture because you can hardly see their faces and it's their fault for not being in class if they were in class then they wouldn't have been in the photo, they also would've saw me holding the camera so that too is on them. Reflective hallway I call this image reflective hallway because of how the light source (natural light) reflects the lockers in the hallway. I also like how the hallway leads to the a window that doesn't have a natural glow but is also foggy and gray. Even though it is foggy and gray and doesn't give you that warmth and comfort the light still fits in the photo and it still keeps the photo looking good. I like the doors at the side of the hallway too, it creates a little more personality and setting to the photo. The only thing I think I might dislike in this photo are the lights above. Mostly because I just don't like how they look like. The natural light made it easy to control the triangle aspect of the image. Reflective Hallway Texture Of A Garbage Can This image mainly focuses on the texture a garbage can. My partner at that time (Roah) held the doors for me so I won't have to go to the front of the school. I think that was my main challenge of taking the picture... Holding the doors open. When you look at the texture of the garbage can it's almost like you can feel it. The hard pebbles leading to grainy sand of the garbage. This image tells us that even everyday things like garbage cans can be fit for a perfect photo. I had to adjust the aperture to make the ISO fit the type of lighting I had because it was very cloudy. But the cloudiness actually made the photo better Texture of A Garbage Can Team effort I like this photo because it shows the girls basketball team and everyone working and taking care of each other. It also reminds me of the friendship the girls have for each other. This image also reminds me of them winning that day and how hard they've worked. Team effort Endless hallway I like this photo because it was one of my first photos I took in photography when we were able to take the cameras out. I like the details in the photo and it really shows my creativity too. I also like photos with trippy long hallways and this photo shows the beginning of that. Endless Hallway Flower power I like this photo because it's from my garden and it shows all the work my parents put in the garden too. When I see this photo I imagine the rose to be soft and smell fresh and lovely too. I also like

Great Waves

Transcript: Conclusion As soon as I saw the wave pool, slides, playground, kiddie pool, splash park, and the shark shack, I got happy and excited. I touched the hot sand and the cold water which had the waves in it. I played on the hot playground that made me sweat. Introduction In summer of 2012, I visited Cameron Run Water Park for summer break.I was there for 90% of the summer. In addition, I heard geese by a pond. I heard splashes when people jumped into the pool. I also heard when the lifeguard blew his whistle. Finally, I heard the screams from the slide. Great Waves By Malachi Dickson Body
