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...

The intensity of a light wave is similar to what we think of as brightness. If an EM wave is emitted from a point source, the intensity of the way [ Select ] grows with the distance from the source as r^2 decreases with distance as 1/r^2 Consider light incid grows linearly with distance from the source, decreases with distance as 1/r very smooth, meani is constant, independnet of distance from the source is [ Select ] • , then...
