Hello everyone. I wanted to make sure I did this problem correctly. The problem is this:
A light with an intensity of 75 W/m^2 is shone through three polarized lenses. The first lens is tilted at a 37 degree angle, the second is at a 10 degree angle and the final lens is titled by 82 degrees. Find the final intensity of the light.
So this is my work:
75 W/m^2 X 1/2 (half of the light is filtered through the first lens) X cos^2(37-10) X cos^2(82-10) = 2.84 W/m^2
Is this the proper way to do this problem? This is the way our example from class was calculated, but I was a little bit hazy on the details, so I wanted to make sure that I did the work right. Thank you all.
