Light of wavelength 500 nm is incident perpendicularly from air on a film 10-4 cm thick and of refractive index 1.375. Part of the light enters the film and is reflected back at the second surface. How many “wavelengths” are contained along the path of this light in the film? What is the phase difference between these reflected waves as they leave the film at the first surface?
