Problems. 1. A uniform, thin film of alcohol (n = 1.36) lies on a glass plate (n = 1.56). A light source whose wavelength can change is incident on the film. Constructive interference occurs at a wavelength of 655nm, destructive interference at 525nm. What is the minimum thickness of the film? (Hint, m is NOT equal to one here!) 2. A photon of momentum 3.53 X 10-28 kgm/s is emitted from a hydrogen atom. Find the initial and final states of the electron that emitted this photon. (The table on page 792 might be useful)
