Polarisation of Light
question_answer
Polarising angle for water is 53°4'. If light is incident at this angle on the surface of water and reflected, the angle of refraction is [TNPCEE 2002]
A) 53°4'
B) 126°56'
C) 36°56'
D) 30°4'
Correct Answer:
C
Solution :
\[{{\theta }_{P}}+r=90{}^\circ \] or r = 90o ? qP = 90° ? 53°4' = 36°56'.
