Light is incident on a glass surface at polarising angle of `57.5^(@)` Then the angle between the incident ray and the refracted ray is

Options

A. `57.5^(@)`
B. `115^(@)`
C. `65^(@)`
D. `205^(@)`

Answer

D

Explanation

When light ray incident at polarising angle, then angle of incidence (i) and angle of reflection ( r) are equal. Also, angle between reflected and refracted ray is `90^(@)`.

Thus, angle between incident ray and refracted rays
`=57.5^(@)+57.5^(@)+90^(@)=205^(@)`
