Problem 80GP

At what angle should the axes of two Polaroids be placed so as to reduce the intensity of the incident unpolarized light by an additional factor (after the first Polaroid cuts it in half) of (a) 4, (b) 10, (c) 100?

Step-by-Step Solution:

Step-by-step solution

Step 1 of 4  

 ; the intensity of unpolarized incident ray.

 ; the intensity of light  after passing through the first Polaroid.

; the intensity of the after passing the second Polaroid.

         

The first Polaroid cuts the half of the incident light.

         

Step 2 of 4</p>

b)the second Polaroid is rotated to so that the intensity of the transmitted ray reduces to one forth.

         

         

Step3 of 4

b) the second Polaroid is rotated to so that the intensity of the transmitted ray reduces to one tenth.

         

         

Step 4 of 4</p>

c) the second Polaroid is rotated to so that the intensity of the transmitted ray reduces to one onehunderth.
