Question

Part A:

A ray of light is incident onto the interface between material1 and material 2.

Rank these scenarios on the basis of the phase shift in thereflected ray

Part B:

Rank these scenarios on the basis of the phase shift in the reflected ray

Answer 1

For part A: There is no phase shift in the refracted ray, therefore all the choices are equivalent (0) and should be overlapped.

For part B: The only thing that matters is which of the indices (N1 or N2) is larger. The phase shift in the reflected ray is larger if N2 is larger than N1. Using the numbers assigned by the previous answer, 2, 3, 4 and 5 are equally larger than 1 and 6.
