An EM wave with a maximum electric field of 19V illuminates a surface with an area of 0.50ms. The EM wave is incident on the surface at an angle of 37◦ to the surface normal. Compute the force on this surface, if the wave is reflected completely.

Given the same intensity of light, radiation pressure from totally reflected light is half as much as from totally absorbed light. O True O False

Two electromagnetic waves are represented by the following expressions: E = Ae(k=-wt) En Ē2 = Ae"(kz-wt+a), where both A and a are real. (a) For each wave, determine its polarization state. Calculate the time-average Poyning (s). vector Consider the superposition of the two waves E3 = E1 + E2. (b) Calculate the time-average Poyning vector (5.). (c) For what value(s) of a will E, be a circularly polarized wave?

RF Electromagnetics: . If an x-component of the E-field varies as a sine function, and y-field component varies as a cosine function; assuming that the Ex=0.7Ey, what is the polarization of the resultant wave whichpropagates in the positive z-direction. For frequency f, write the full expression for the electricfield of a plane wave propagating in vacuum.
