Find the intensity of reflected and transmitted waves through an interface between two linear non-conducting media in terms of the intensity of the incident wave and the indices of refraction of the two media. Note: To do this, suppose a plane wave of frequency ω and electric field polarization in the x direction is traveling in the positive z direction. The wave approaches the interface between two media on the xy plane from left. Write complex waves equations for the...
