Chapter 16, Problem 9E

An antireflection coating is designed with a thickness of a quarter of the wavelength of the light travelling in the film.

a.    How many wavelengths farther does the light reflected from the bottom surface of the coating travel than that reflected from the top surface?

b.    Does this produce constructive or destructive interference?
