Solve the following problem given below:
Problem: A soap film has an index of refraction n = 1.62. The film is viewed in transmitted light.
Part I: At a spot where the film thickness is 966.0 nm, which wavelengths are missing in the transmitted light? (Enter your answers in order, least to greatest, from left to right. If there are more than 3 such visible wavelengths, enter the 3 smallest.)
Part II: Which wavelengths are strongest in transmitted light? (Enter your answers in order, least to greatest, from left to right. If there are more than 3 such visible wavelengths, enter the 3 smallest.)
I want you to clarify the physics in this above problem.
