Question

The reflected ray is completely polarized when a ray is incident at a medium of refractive index 1.73 then value of angle of refraction

Answer 1

Answer:

Here n=1.732

(i)According to Bewsters law, tan ip=n

Therefore polarizing angle ip=tan-1 n

=tan-1(1.732)

=600

(ii) At the polarising angle, the reflected and the refracted ray are perpendicular to each other.

Therefore angle of refraction r = 900 - ip

=900 - 600

=300
