Obtain what is the minimum thickness of the film

Reference no: EM13660200

A thin film of soap with n = 1.38 hanging in the air reflects dominantly red light with λ = 699 nanometer. Calculate the minimum thickness of the film?

Now this film is on a sheet of glass, with n = 1.51. Find the wavelength of the light in air that will now be predominantly reflected?
