Determine the refractive index of the film

Reference no: EM13694133

Question: A tank of gasoline (n = 1.40) is open to the air (n = 1.00). A thin film of liquid floats on the gasoline and has a refractive index that is between 1.00 and 1.40. Light that has a wavelength of 592 nm (in vacuum) shines perpendicularly down through the air onto this film, and in this light the film looks bright due to constructive interference. The thickness of the film is 200 nm and is the minimum nonzero thickness for which constructive interference can occur.

Part A- What is the refractive index of the film?

Hello Experts please provide me the detailed calculation for above question.
