GOAL Understand how polarizing materials affect light intensity. Unpolarized light is incident upon three polarizers. The first polarizer has a vertical transmission axis, the second has a transmission axis rotated 30.0 degree with respect to the first, and the third has a transmission axis rotated 75.0 degree relative to the first. If the initial light intensity of the beam is I_b, calculate the light intensity after the beam passes through the second polarizer and the third polarizer. After the beam...

The diagram below shows a beam of light shining through three
linear polarizers in a row. The polarizing axis of each polarizer
is measured at an angle (ϴ1,ϴ2,ϴ3) from vertical.
Suppose that the original beam of light emanates from a
vertically polarized laser. The laser has a power output of 1 mW
and the beam has a diameter of 2 mm. What is the intensity of the
laser beam before it travels through any polarizers?
