Unpolarized red light is incident on the...

Unpolarized red light is incident on the surface of a lake at incident angle `theta_R`. An observer seeing the light reflected from the water surface through a polarizer notices that on rotating the polarizer, the intensity of light drops to zero at a certain orientation. The red light is replaced by unpolarized blue light. The observer sees the same effect with reflected blue light at incident angle `theta_B`. Then

C
