Minimum Thickness of a film with wavelength and index of refraction.

LadiesMan

1. If the index of refraction of you soap was 1.35, calculate the (minimum) thickness of the film at that part of the film that appears green, given that in air, green light has a wavelength of 535 nm.

2. x = L(lambda/2t)

3. I can't figure out how to derive the equation with n (index of refraction)
