The drawing shows four sheets of polarizing material, each with its transmission axis oriented differently. Light that is polarized in the vertical direction is incident from the left and has an average intensity of 30 W/m². Determine the average intensity of the light that emerges on the right in the drawing (a) when sheet A alone is removed, (b) when sheet B alone is removed, (c) when sheet C alone is removed, and (d) when sheet D alone is removed.

The electric component of a beam of polarized light is Ey=(5.21 V/m) sin((1.08 x 106 m ¹)z + wt]. (a) Write an expression for the magnetic field component of the wave, including a value for w.

A wave is passing through two polarizers. It is an unpolarized electromagnetic wave, and it initially has a max electric field magnitude of 20000N/C. The 1st polarizer, polarizes at an angle of 20 degrees vertical. The 2nd polarizer, polarizes at an angle of 30 degrees horizontal. What would be the intensity of a light wave that passes through the two polarizers?

From a local TV station transmitter, a sinusoidal, plane electromagnetic wave is normally incident on an open window that has an area of 0.510m2. The wave travels to the right in the positive x-direction at the speed of light c and the window is thus perpendicular to the x-axis. See the schematic. Suppose the three electric field components have wave functions: EX = 0 EY = Emsin(kx-ωt) EZ = 0 See the axes below. At the moment shown the electric field - indicated by the vertically upward arrow - points in the positive y direction. Assume the field magnitude Em = 0.01000 V/m. The Erms (root mean square) of the electric field would thus be Erms = 0.00707 V/m. (a) At the moment shown above, in what direction does the magnetic field point? Indicate this direction by drawing a symbol near the z-axis. (b) Compute the numerical value of amplitude Bm of the magnetic field component pointing in the direction you found.
