A 610-nm thick film, of index n1 = 1.45, is on the surface of a glass plate, of index n2 = 1.55. A ray of monochromatic light, of 550-nm wavelength, is incident normally upon the air-film interface, and undergoes reflections and transmissions. Consider points A, B, C, and D as being at a neglible distance from their nearest interfaces, respectively. Determine the phase difference (in radians) in the waves at B, with respect to the wave at A.
Please show Formulas and work. Thanks!
Answer = 11 radians
