What is the thickness of the film

Reference no: EM13543665

A thin film of acetone (n = 1.25) coats a thick glass plate (n = 1.50). White light is incident normal to the film. In the reflections, fully destructive interference occurs at 600 nm and fully constructive interference is seen at 700 nm. No other destructive or constructive fringes are observed in between those fringes. What is the thickness of the film?
