Question

The velocity of light  in air is 3 x 108 ms-1 and that in water is 2.2 x 108 ms-1. The polarizing angle of incidence is

1)  45o      2) 500      3) 53.74o     4) 63o


​

Answer 1

Answer:

c) 53.74

Explanation:

R.I (n) = v in air / v in water

     n=1.36

tan theta= n

               = 1.36

theta = 53.74 o
