In the case of refraction, there is no phase change. But in reflection, phase changes by 180 degrees.
So in this question, two times reflection occurring,
So total no. of 180-degree phase change= 2

A light ray in air (n= 1) is incident on a thin film of oil (noil = 1.60) floating on top of water (nwater = 1.33), as shown below. The wavelength of the incident light in air is Aair = 640 nm. The oil layer has a thickness t = 0.5 um. The ray is assumed to be incident practically along the normal. That is, we won't be worried about angles of reflection or refraction when doing this problem. However,...
