8a: a light wave of amplitude E sub 0 = 1 traveling in the +z direction is incident on a slab of glass, refractive index n=1.5, at perpendicular incidence. It has wavelength λ = 2π/k in vacuum. Determine the reflection coefficient, R, and transmission coefficient, T for the wave. b. Now assume that the slab has thickness a, meaning its boundaries are located at z = 0 and z = a. Assume it is infinite in all other directions. In...

A multilayer transparent block is made of a layer of cubic zirconium, CZ, (n=2.18) attached to a layer of quartz (n=1.54). The block is in air. Laser light enters the block from the CZ side with an incident angle of 27 degrees. The light exits the bottom of the block going from quartz into air. a. Sketch the block in air with a ray diagram of the path of the light from air, into cubic zirconium, into quartz and out...
