Exercise 3A: Looking at Different Colors of Light Case 1. It would read nothing, except when the detector was at the particular angle where the green light beam hit it and there it would read a signal. Case 2. It would be zero (flat), except for a narrow spike at the angle for green light. Case 3. It would look just the same except the spike would be half as high. Case 4. Your eye sees the combination of red and blue light as purple, but after it goes through the prism it is split into separate red and blue beams. This gives a spectrum with two spikes one at the angle where blue light comes out and one at the angle for red light. Case 5. Sunlight is made up of all the colors of the rainbow. So there is a signal at all the angles corresponding to those wave lengths. However in contrast to what you might have expected the signal does not go down immediately when the detector gets to angles larger than violet or smaller than red where you do not see any colored light beams hitting. The detector can detect this light however and so it shows signals. Exercise 3B: Electromagnetic Waves Case 1. The wavelength of green light (540 nm) is smaller than that of red light (670 nm) so the wiggles would be closer together. Case 2. Violet has a wavelength of about 400 nm, so the peaks are closer together than for red light. The separation is smaller by the ratio of the wavelengths 400/670, or about 0.6 as far apart

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
