Fill in a t/f answer for each statement below. if false, correct the statement to make it true.:
1. [ ] for reflection of light, the angle of reflection equals the angle of incidence.
2. [ ] the speed of light is the same in all optical mediums.
3. [ ] the frequency of a light ray is the same when the light travels from one medium to another.
4. [ ] the index of refraction indicates the ability of a medium to bend the light beam as refraction occurs.
5. [ ] when you see a fish in water from a boat, the fish is actually not at where you think it is.
6. [ ] total internal reflection can occur when light travels from vacuum to an optical medium with higher index of refraction.
7. [ ] the reason that a prism can produce a colorful spectrum from a white light source is that its index of refraction is a function of light frequency.
8. [ ] when a light beam of wavelength λ is incident on a slit of width d, the ray approximation is valid when λ ≈ d.
9. [ ] optical fibers rely on total internal reflection to prevent light lose at the surfaces of the fibers.
