The figure shows the vertical interface between two transparent
materials with different indices of refraction. You do not know the
exact value of

is possible for light rays incident on the interface from the right
side.
Given this information, which of the numbered rays is a possible
refracted ray for the incident ray shown?

[3] A uniform plane electromagnetic wave (UPEMW) propagating in a lossless nonmagnetic dielectric half-space medium with εr = 16 is incident obliquely at the interface plane with another lossless nonmagnetic half-space with εr = 4. The two dielectric half-spaces are in intimate contact with each other at the interface plane z = 0. The incident UPEMW is polarized in the plane of incidence. The angle of incidence is 60° to the normal to the interface plane. Find the fraction of...

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...
