Wave Effects Assignment 4. Light as a Wave https://youtu.be/IRBfpBPELmE?list=PL8dPuuaLjXtNOge7yDk UAOldZJahwkoV Or web search: "Crash Course Physics #39" In the video, Dr. Somara discusses what happens when a wave passes through a slit or past an object. Explain, in your own words, why there is a bright spot in the center of the coin's shadow: 5. Rainbows https://ophysics.com/117.html (if you type it in it is a lower case L then 17) Or web search: "oPhysics Rainbow Formation" Rainbow Formation C The screen at right will come up. If you click on "Spread" you will see one raindrop's contribution to a rainbow. Play around with the sun angle and see what it does. Is a rainbow produced at every angle? 1. Is a rainbow due to refraction, reflection, or diffusion? Why do you say that? Now click on "Zoom Out" and set the "Spread Amount" to "Realistic." Check both "Show Primary" and "Show Secondary" Reflection Rays. Move the sun position around until you see two sets of red and blue rays visible from the ground. Each of these would form a rainbow, one inside the other. Click "spread" to check whether they both contain all the colors or not. If not move the sun a bit more. 2. Why are there two rainbows forming? What causes the secondary ring of colors? 3. What do you think you can see in the space between the two rainbows based on the diagram
