When watching the Moon over the ocean, you often see a long streak of light on the surface of the water. This occurs because (choose the best answer)   the Moon is very large.   The atmospheric conditions are just right.   The ocean is calm   The ocean is wavey   Cool ocean air causes a mirage.

What happens to a light wave when it hits a surface that has a higher index of refraction? a)  It reflects with λ/2 phase shift.  b) It reflects with a λ/4 phase shift. c) It's shift is porportional to the angle of reflection.  d) It reflects with it's phase unshifted.

A gemstone (n = 1.72) is submerged in oil (n = 1.45). A light ray in the gem is incident onto the surface at 45 degrees. Will the light refract into the oil? Yes No

Calculate the critical angle for light to travel from glass (n = 1.56) to water (n = 1.33).

The index of refraction for water is about 4/3. What happens to light when it travels from air to water? Its speed decreases to 3c/4, and its wavelength decreases by a factor of 3/4 Its speed decreases to 3c/4 and its wavelength increases by a factor of 4/3. Its speed increases to 4c/3, and its frequency decreases by a factor of 3/4. Its speed decreases to 3c/4, and its frequency increases b 4/3.

A point source of light is submerged 2.30 m below the surface of a lake and emits rays in all directions. On the surface of the lake, directly above the source, the area illuminated is a circle. What is the maximum radius that this circle could have?

The incident angle is 60°, in which of the following situation would you observe Total Internal Reflection? nwater = 1.33, nglass= 1.50.
