Question

A ray of light is incident at an angle i while travelling from denser to rarer medium. The reflected and refracted rays are mutually perpendicular. If the angle of incidence is 30°, then the refractive index of rarer medium w.r.t denser medium is

Answer 1

Answer:

angle at which the refracted and reflected rays are perpendicular to each other is called as brewsters angle .at this brewster angle the tangent of the brewster angle is equal to the refractive index of the denser medium.so , back = to index of the medium = tan(30°)=1/ V3 Hope this answers help you.
