Question

The circle below gives you a reference for the angles referred to in this problem. A particular beam of light, with an intensity of 300 W/m2, is unpolarized at an angle of +6.00 degree to the vertical. You have three polarizers, which have their transmission axes aligned as follows: Polarizer A - the transmission axis is at +14.0 degree to the vertical; Polarizer B - the transmission axis is at +73.0 degree to the vertical; Polarizer C - the transmission axis is at +28.0 degree to the vertical. (A) If you want to maximize the intensity of the light emerging from the second polarizer, which two polarizers should you select, and in what order should the light pass through them? (B) For that situation in (A) what is the intensity? (C) If you want to minimize the Intensity of the light emerging from the second polarizer, which two polarizers should you select, and in what order should the light pass through them? (D) For that situation in (C) what Is the Intensity?

Explanation / Answer

We know

I=Io*cos(theta)*cos*(theta)

So for maximum theta should be minimum as lesser the theta,more will be cos(theta)

So choose A and C and first it should pass through A

Intensity=276.97

For minimun theta must be maximum so choose A and B

And first. It should pass through B

I=12.15 W/m*m
