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 30degree from the vertical, and the third has its axis along the horizontal. (a) What fraction of the light intensity comes out of the filter? I_f/I_0 = (b) What fraction makes it through the system if the...
Consider three polarizing filters oriented as shown in the figure below. A beam of unpolarized light is directed through the three filters.

An unpolarized beam of light with intensity 3 MW/m2 passes through two polarizing filters. The first filter is vertically polarized, and the second filter has a polarization axis 15 degrees away from horizontal. What is the intensity of the beam that exits the second filter?
Light that passes through a series of three polarizing filters emerges from the third filter horizontally polarized with an intensity of 225 W/m2. If the polarization angle between the filters increases by 25° from one filter to the next, find the intensity of the incident beam of light, assuming it is initially unpolarized.
A beam of polarized light passes through a polarizing filter. When the angle between the polarizing axis of the filter and the direction of polarization of the light is 29 ∘, the intensity of the emerging beam is I A) If you instead want the intensity to be I/2, what should be the angle between the filter axis and the original direction of polarization of the light?
Light that passes through a series of three polarizing filters emerges from the third filter horizontally polarized with an intensity of 230 W/m22. 1) If the polarization angle between the filters increases by 25∘∘ from one filter to the next, find the intensity of the incident beam of light, assuming it is initially unpolarized. (Express your answer to two significant figures.)
Consider a sequence of ideal polarizing filters, each with its axis making the same angle with the axis of the previous filter. These polarizers rotate the plane of polarization of a light beam by a total angle of 45◦ . a) In order to have no more than a 10.0% reduction of intensity, what is the minimum number of polarizers needed? Hint: The equation you will set up to solve this will be transcendental, so it is impossible to solve...
Light that passes through a series of three polarizing filters emerges from the third filter horizontally polarized with an intensity of 280 W/m2. 1) If the polarization angle between the filters increases by 25° from one filter to the next, find the intensity of the incident beam of light, assuming it is initially unpolarized.

#18. Cameras often use polarizing filters to reduce glare. What angle would the axis of a polarizing filter need to make with the direction of polarized light of intensity 116 W/m2 to reduce the intensity to 10.0 W/m2? (θ should be between 0° and 90°.)
Two polarizing filters are placed in a sequence, as shown in the schematic diagram. Unpolarized light is incident on the first filter, and any light that passes through the first filter is incident on the second. The lines drawn through each filter indicate the direction of its polarization axis. Identify the light polarization at each step in the process by dragging the appropriate image into each box. unpolarized light no light Polarizer 1 Polarizer 2 Answer Bank no light unpolarized...
