After a hard rain, you walk out into the parking lot and notice an oil sheen on top of a puddle of water. When viewed from directly above, the light reflected off the puddle is a bright red which you estimate to be a wavelength of 680 nm. The index of refraction of water is nwater = 1.33 and the index of refraction of the oil is noil = 1.47.

a) Does light reflected off the top of the oil have a phase shift? Yes/No.

b) Does light reflected off the bottom of the oil have a phase shift? Yes/No.

c) What is the minimum thickness of the oil?

d)What wavelength of light is transmitted into water most effectively?
