Monochromatic light of variable wavelength is incident normally on a thin sheet of plastic film in air.

Question:

Monochromatic light of variable wavelength is incident normally on a thin sheet of plastic film in air. The reflected light is a minimum only for λ = 512nm, and λ 640nm in the visible spectrum. What is the thickness of the film (n = 1.58)?
