Suppose a certain wavelength of light falls on a diffraction grating and creates an interference pattern.
1. What happens to the interference pattern if the same light falls on a grating that has more lines per centimeter?
2. What happens to the interference pattern if a longer-wavelength light falls on the same grating?
3. Suppose a feather appears green but has no green pigment. Explain in terms of diffraction.
4. Why is the index of refraction always greater than or equal to 1?
5. Draw how light changes direction (toward or away from the perpendicular) in the following situations:
6. goes from air to water?
7. goes from water to glass?
8. goes from glass to air?
9. Why does the wavelength of light decrease when it passes from vacuum into a medium?
10. Describe the types of images the following “devices” can create, and where the object needs to be located in relation to the “device” for that type of image to occur. Be clear in discussing all cases.
11. a convex mirror
12. a concave mirror
13. a convex lens
14. a concave lens
