What is the thickness of the film now

Reference no: EM13549520

You are coating a glass lens of index of refraction 1.6 with a film of material of index of refraction 1.7. You start with the thinnest film possible that creates a strong reflection for 560 nm light. You gradually increase the film thickness until you again get strong reflection. What is the thickness of the film now?
