Refraction

refraction

The image shows refraction with a converging lens. This is refraction because the image is resized and upright. The converging lens is indented in the center, so it takes in light and resizes the image to look smaller.

Reflection.

 

This illustrates, reflection since the other item could be seen of the guitar polished board. the light reflecting on the board, has enough light for it to reflect the image of the other things that could be seen, and it follows the  law of reflection too.

The windows are similar to a mirror because as you can see, the windows above are getting reflected off of the blue windows. It acts as a mirror and reflects the same real image exactly like the original image. Frankie covello

This photo illustrates reflection of light by showing an inverted image of the original image, which we would call a real image.

This is a picture of reflection. The light bounces off the window and forms the same image an equal amount of distance from the reflection point. It acts as a mirror because it is reflected similar to a mirror.

This photo demonstrates both reflection and refraction. This picture is of a poster that has a glass cover on it. Depending on the angle of light you could either see the light refracted from the glass and the poster itself or you could see a reflected image of whatever/whoever walked by. In this picture i captured an reflected image of a few students walking past while also having the poster in focus. You can also see the reflected image of the hallway and the ceiling lights.

Mirror and Lenses Photo project

For this project, I used a diverging lens with a rounded mirror. The lens I used made everything behind it smaller, bending the light. The mirror I used also reflected everything smaller because it had a slight curve like one used on a car. I used this and the mirror to make my face much smaller than it would be with a regular mirror.

 For this project, I used  a converging lens on a extensions packet to show refraction. When I put the lens over the packet, the words on the packet are flipped upside down. This is because the light going through the lens is being bent or is being refracted causing our perception of the image through the lens to be reversed. To be more specific, the light goes through the focal point to create this reversed and reduced image.

          In this picture, I used two diverging lenses to see the red cup. I saw the red cup through both of these lenses by reflection. First, I placed the red cup on the table then I held up one of the diverging lenses to see the cup. Through the one lens, the cup looked like it a lot farther away then it actually was. Then, I decided to put a second lens in front of the first one which made the cup look like it was even more farther away. The way this worked was the with the first lens, the cup reflected off the lens which is why I was able to see it. Same thing happened with the second lens, it reflected off the first, then the second which is why I could see the red cup through both lenses.

My photo reflects refraction. We know this is refraction because our image is right side up, enlarged and real. This image is right side up, enlarged,and real due to the fact that the lense was convex. Convex lenses are flat and when you pull the lens away, the image becomes magnifyed.

Picture one illustrates the red and the blue mixing shows a clear picture of the color magenta. The blue and green combine and make cyan. Picture two is a great picture because it really demonstrates all the colors very well. The red and green show yellow very well. The blue and green and a great cyan color and green red and blue make WHITE!! And if you look at the bottom the red and blue intersect it makes magenta but it is hard to see and that's why i took a picture of picture one. These lights look great!

Finding speed of light using microwave and CHEESE by Amb Boswell

To find the speed of light using a microwave I first looked at the inside of my microwave to find the Frequency. The frequency listed was 2.45 billion . I then put cheese on a piece of bread and microwaved it for 20 seconds. I noticed two spots that were more melted than the rest of the cheese. I measured the distance between these two spots, which was 5.8 cm. To find the speed, I used the equation: v= Frequency(2.45billion) times the wave length (5.8*2=11.6). So 2,450,000,000 * 11.6= 28,420,000,000. I then divide this number by 100, to convert centimeters into meters. So for my final answer I got 284,200,000 m/s  The actual speed of light is 299,792,458 m/s. So I am just slightly off. 

In this experiment, I spread butter on a piece of bread and looked at where it melted to discover the wavelength of that oven. Afterwards, I looked on the the inside of the oven cover to find the output of the oven. Using these measurements i was able to form this equation. 2,450,000,000H * 12cm Which came to 2.940x10^10. Seeing as how the speed of light is around 299,792,458 m/s, my conclusion isn't particularly far off the mark.  

3d Photo

This photo was created by taking one photo with a digital camera, moving the camera around 8 cm to the left in order to take the image on the right, then i put the two together in photoshop in order to create the 3d effect.

Vincent Case

We took a photo of the stairs and took another after covering our left eye. We then uploaded the photos on Adobe Photo Shop to create the 3D effect. The 3D effect works using the 3D glasses because your left eye sees through the red filter while the right sees through the blue filter. When combined you see the two images as one which gives it the 3D effect. All one needs to do is use 3D glasses regardless of how far one is from the screen.

Photo #1

Photo #2


Photo #1 illustrates color addition. Magenta and cyan can be combined together to appear blue. Magenta and cyan are complements of the primary light colors red and green. In the color wheel, it shows that when blue and green are combined, they make cyan. When red and blue are combined, they show magenta. This means cyan and magenta both have complements of blue. When cyan and magenta are combined, magenta's green is absorbed, leaving blue, and cyan's red is aborbed also leaving blue. In the end, the light that appears is blue because the complements are being aborbed and the blue is left over.
Photo # 2 illustrates color subtraction because when cyan and red are combined, no light appears. These two colors create no light, or black, because cyan and red are complements of eachother. Red absorbs cyan light, and cyan absorbs red light. Since they both absorb eachother, they block light. It appears black.

I made my glasses 3D. First, I took two pictures (the second one being moved slightly), then I uploaded them to my computer and turned on a grayscale fliter. After that, I turned one image to full cyan and the other to full red. When I had done that, I created an RGB layer for one of them and pasted the opposing image onto its layer. Finally, I made a few slight adjustments and got a 3D photo.
This works because when you have two opposing colored filters (in this case red and cyan) they pop out more due to not being able to blend with each other well.
All you need to be able to see these 3D glasses are 3D glasses.

     I made this 3D photo by taking a picture of the same object twice. I made the photo by opening the photos in photoshop and followed the directions on the NASA website. I had to make it have a 3D effect so we made the picture turn gray and added colors to the picture. The 3D effect worked with colored filters because the colors im trying to make show up is the red, blue, and green color. You need to wear 3D glasses in order the see the 3D image.

This picture shows collor subtraction in it's most basic form, where a red light is shined on a white board.  However, the cyan sheet in the picture absorbs red light, and since there is no green or blue light. the covered part appears black.

Syed and Nathan's 3D blog

took 2 pictures of me in different perspective, uploaded to photo shop and then put up both pictures to gray scale. put both back to RGB and took 1 picture and made it red and finally to complete it we put it together. to see the photo pop out you need the 3d glasses to see it happen.

First we used Adobe Photoshop to construct two photos that we put together to make a 3-D photo. When we grayscaled the photo and used the color red over it, it visible that the pictures together were 3-D. The 3-D effect is produced using color filters. Using two pictures, causes the 3-D effect because our eyes see depth within the two pictures and when we changed the coloring to RGB and wore the glasses it made the pictures look 3-D. Our eyes are about 2-3 inches apart which causes each eye to see the picture from different angles. Our eyes see 3-D because the red and blue from the colored filters contrast. In order to see the 3-D picture, you need to use the color filters so the colors can contrast and your eyes can see at different angles. (3-D glasses)

Color Addition/ Subtraction Photo.

Before: (RGB lights)       

 After: Cyan Filter

After: Yellow filter

After: Magenta Filter

                Filters are used to absorb certain primary colors (RGB) of light and allow any left over primary colors (RGB) to be transmitted. When these primary colors hit a colored filter (CYM), certain primary colors appear, but some cannot be seen. As shown, when RGB hits a Cyan filter, only blue and green appear (transmitted), but  red is being absorbed, so you cannot see it very well. Next, RGB is shined on a yellow filter, but this time, just Red and Green are being transmitted, and blue is being absorbed. Lastly, to prove the color addition/ subtraction model, I used a magenta filter. Red and blue are transmitted, so they are visible, but green is absorbed, and not visible.

The first pictures in these posts show what the lights look like without any filament in front of them. In the second photo, you see these red, blue, green lights covered by a yellow, magenta, and red filament. The green light now looks cyan now because blue and yellow make cyan. The green light now doesn't show because it is covered by a magenta filament and green and magenta absorb each other. The red light still looks red because it is covered by a red filament which does nothing to the light passing through.

Standing Waves Photo Project - Banipal Georges

NOTICE: This is a 6th harmonic string, the last loop was cut out.

I started by finding the entire string's length which was 294cm. After that, I divided it by 3 to find the length of one wave (I divided that by 10 to convert it to meters). Finally, I multiplied that by the frequency, 41 Hertz, to get a speed of 40.18 m/s.

I turned off the flash on the camera to avoid heavy brightness.

Standing Waves Photo Project by: Hope & Syed

We determined the speed of the wave by finding out how many antinodes there were. Since there were 5 all together, and two of the wavelengths equaled a whole. We multiplied 87, which was the total wavelength, by 34.8 which was the frequency that we started off with and we got a velocity of 3027.6m/s.
