Mirrors and Lenses Photo Hannah

This photo displays reflection and refraction in many ways. One way it displays reflection is, the light from the sun reflects against the camera lens. Another way this photo displays refraction is, the camera breaks up the sunlight. You can tell from this that this forms a ray. The sun appears blurry in this picture because of the lights rays being reflected and refracted.

Candace and Cecilia Mirror and Lenses Photo Project.

This image shows the reflection of light in a lens. It shows reflection because the shutter is held open while the lens is capturing the movement of the light, which happens to be a flashlight. It is created by the movement of a light using a slow camera shutter speed, to create an image. Because this type of photography requires a long exposer, it is usually dont at night, or in this case, a dark room.

Create Your own 3-D Photo Farhad, Candace and Cecilia

`This was a picture took in Physics class to show 3D effect. The picture was edited in phtoshop to give it it's 3D effect. We took two pictures one picture was the main one, the other was exactly 3 inches to the right of the normal picture. We removed RGB the three main colors from the first photo, which gave it it's faded black and white colors. Then we merged the 2nd picture with the first picture and we saw three colors black blue and red, and this is why we got a 3D effect. This works because if there is two pictures from a distance attached with no colors then you see the picture as one. You see the picture as one picture with the same color. The only way you see this picture in a 3d effect is with 3D glasses that have red and blue lenses.

Farhad-Measuring the Speed of Light in Your Microwave

 

 To find the Speed of light I had to recall the wave equation, which is v=λf. To find the wavelength I had to do an experiment. First I grabbed a slice of bread, I added a thick layer margarine to the top. Then I put it in the microwave for 40 seconds to let the margarine melt. After the 40 seconds, I took it out and got a ruler to measure the "hotspots". The "hot spots" were about 4cm, I converted cm to meters. Then I did my calculations. The wavelength was 0.04m, the frequency was 300mHhz.The velocity is 12m/s

Color addition Farhad

This is a picture of lights. You can see the red and blue lights being mixed together making a magenta color. The blue and green lights also mix to make cyan.

Color Addition Candace and Cecilia

This picture shows the addition of color by adding food coloring to the water. When you mix all the colors together you get black, but as you can see when you mix the red and blue it makes a deep magenta color. Also, when you mix the blue and the green food coloring you get cyan. 

Measuring the Speed of Light in Your Microwave -Cecilia and Candace

 In this experiment we found the speed of light. Microwaves create standing waves. The antinodes are the "hot spots". First I got a slice of bread and I added a thick layer of margarine on top. Candace put it in the microwave for 50 seconds. We watched the margarine melt. Then I took the slice of bread out of the microwave and Candace got a ruler and measured the "hot spots". The "hot spots" were about 6cm. The wave equation is v= λf. the wavelength is 6cm. the frequency is 2450mhz which I got from my microwave label. I converted cm to meters. I did 0.06m x 2450m = 147000. the velocity is 147000m/s.
