please answer all the parts
A uniform plane wave in a dielectric medium (?1-0, ?,-4e0, ?,-?.) with E- 20 cos (ot – 4x -3-) a, V/m is incident on a dielectric slab (?2-0, ?,-2??, ?,-?.) (2 0). Find: a) The polarization of the wave with respect to the plane of incidence (b) ki, o. ? (c) The critical angle ?' and the angles ?, ? (d) The reflected wave e) The transmitted wave
