Aright-hand elliptically polarized plane wave with a frequency of 1 ghz is propagating in the positive z-direction in free space.

(a) if at any plane z=constant, the ratio of the maximum to minimum value of the electric field intensity is 3 and the maximum value of the electric field intensity is 1 v/m, find the time-average poynting vector (average power density) of the wave.

(b) if this plane wave is reflected by the surface of a half-space occupied by a homogeneous, isotropic, and non-magnetic (μ = μo) material whose permittivity is denoted by ε, find the angle of incidence in terms off at which the reflected plane wave becomes linearly polarized.

Answer choices? if there is any

Transfer of electrons. hope it !

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
