Answer needed as soon as possible, thank you. When white light shines normally on a thin and uniform film of soap (n = 1.33) in air, the wavelengths 500 nm and 700 nm are most strongly reflected. What is the thickness of the film?
E5. A very thin wire is placed between the edges of two flat plates of glass so that a wedge- shaped 'film' of air exists between the plates. Light with 2 = 700 nm is shone perpendicular = to one of the plates, and interference bands are observed in the reflected light. If there are five dark bands per centimeter, what is the angle of the wedge?
