Three polarizing sheets are placed together such that the transmission axis of the second sheet is oriented at 25.0° to the axis of the first, whereas the transmission axis of the third sheet is oriented at 40.0° (in the same sense) to the axis of the first. What fraction of an intensity of an incident unpolarized beam is transmitted by the combination?
Check Your Understanding Although we did no specify the direction in Example 1.7, let’s say the polarizing filter was rotated clockwise by 71.6° to reduce the light intensity by 90.0%. What would be the intensity reduction if the polarizing filter were rotated counterclockwise by 71.6°’

A planar electromagnetic wave is propagating in the +x direction. At a certain point P and at a giveninstant, the electric field of the wave is given by = (0.082 V/m) . What is the Poynting vector at thepoint P at that instant? (c = 3.0 x 10^8 m/s, ?
initially unpolarized light is sent into a system of three polarizing sheets whose polarizing directions make angles of u1 = 40°, u2 = 20°, and u3 = 40° with the direction of the y axis.What percentage of the light’s initial intensity is transmitted by the system?

If E = electric field and B = magnetic field, is E × B a vector or a pseudovector? Comment: E × B/µ0 is called the Poynting vector; it points in the direction of transfer of energ
Two coaxial parallel disks of equal diameter 1 m are originally placed at a distance of 1 m apart. If both disks behave as black surfaces, determine the new distance between the disks such that there is a 75% reduction in radiation heat transfer rate from the original distance of 1 m.
The minimum change in light intensity that is detectable by the human eye is about 1%. Light is sent through a pair of polarizers whose axes are at an angle of 45° to each other. By what angle should the second polarizer be turned so that the change in the intensity of the light that exists is barely perceptible?
In the figure, initially unpolarized light is sent into a system of three polarizing sheets whose polarizing directions make angles of θ1 = 55°, θ2 = 19°, and θ3 = 47° with the direction of the y axis. What percentage of the light's initial intensity is transmitted by the system?
