In this session, the prerequisites required to understand interference in thin films are discussed. The topics include introduction to Newton’s corpuscular theory of light, Huygen’s wave theory, Young’s double slit experiment, division of wave front and division of amplitude method to get interference, meaning of optical path, comparison between reflection and refraction and effect of reflection on the phase of the wave. 2020-09-22T00:00:00Z
