일반물리학 2 — Interference: Problem 52

52 A thin film (\(n = 1.35\)) coats a thick glass plate (\(n = 1.50\)). White light is incident normal to the film. In the reflections, fully destructive interference occurs at \(600 \text{ nm}\) and fully constructive interference at \(700 \text{ nm}\). Calculate the thickness of the film.
