True of False: 1. When light traveling in air (of index 1.00) reflects off of a thin film of oil (of index 1.45) that is coating a piece of glass (of index 1.50), there is a relative phase shift of half a wavelength (in oil) due to reflection at the film boundaries. 2. A ray of light is incident on a material interface where n2 is less than n1. For incident angles less than or equal to the critical angle,...
