A thin film of material is layer on top of the glass. It has an index of refraction of 1.38. White light is incident normal to plane of film. The layers are air, film, glass, air. At point where light is incident on film, light reflected from plane appears green with wavelength = 525 nm
Determine the frequency of green light in air?
Determine frequency of green light in film?
Find the wavelength of green light in film?
Determine minimum thickness of film that would produce this green reflection?
