A flashlight emits completely unpolarized directed beam of light of unknown intensity. The light passes through a vertical polarizing filter followed by a filter oriented at 30° to the vertical.

Most natural light sources emit"unpolarized light, perhaps better described as "randomly polanzed" light. These light sources emit numerous brief bursts of light whose polarization directions are unrelated, so on average the resulting beam has all polarization angles equally represented. When unpolarized light with intensity In passes through a polarizer, its intensity I is cut in half, regardless of the orientation of the transmission axis of the polarizer: I= 10 Part D One way to produce a beam of polarized light with intensity...
Consider three polarizing filters oriented as shown in the figure below. A beam of unpolarized light is directed through the three filters. The first filter has a polarization axis along the vertical, the second has its polarization axis rotated at an angle of 55° from the vertical, and the third has its axis along the horizontal Polarizer Transmission axis Polarizer Polarizer (a) What fraction of the light intensity comes out of the third filter?
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.

2. An unpolarized beam of light with intensity lo = 98.8 lux is incident on three ideal polarizing filters (lux = ). The axis of the first filter (filter A) makes an angle of 18° with the vertical and the axis of the second filter (filter B) makes an angle of 37° with the vertical. The third filter (filter C) is oriented so that its axis is horizontal. a. What is the intensity and polarization direction of the light after...
