Apply the Fresnel equations that we derived in class along with Snell’s law to arrive at an expression for waves (a) through (e) above in terms of the index of refraction of the surrounding medium n1, the index of refraction of the thin film n2, the incident angle

In thin film interference, an (a) incident wave reflects off of the front interface of the thin film and (b) refracts into the thin film.This refracted wave then (c) reflects off of the back interface of the thin film yet also (d) transmits through the film.This reflected wave then (e) refracts back through the front interface of the thin film in order to interfere with the wave that initially reflected off of the front interface.Apply the Fresnel equations that we derived in class along with Snell’s law to arrive at an expression for waves (a) through (e) above in terms of the index of refraction of the surrounding medium n1, the index of refraction of the thin film n2, the incident angle (?i), the thickness of the thin film d, and the wavelength of the incident light ?. Include a diagram of the light rays and give the expression for the path length through the thin film.
