Question

A linearly polarized electromagnetic wave has an average intensity of 324 W/m2. This wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). Polarizer A is oriented with its transmission axis at an angle of θ1 = 40.0° with the incident electric field. Polarizer B has its axis at an angle of θ2 = 70.6° with the incident electric field, as shown in the figure.

The two transverse waves shown in the figure(Figure 1) both travel in the +z direction. The waves differ in that the top wave oscillates horizontally and the bottom wave oscillates vertically. The direction of oscillation of a wave is called the polarization of the wave. The upper wave is described as polarized...
