A light ray is travelling from air to medium, c is velocity of light in air and v is velocity of light in medium. The reflected and refracted rays are perpendicular to each other. The angle of polarisation is

A ray of light is travelling from glass to air. ("Refractive index of glass =1.5") . The angle of incidence is 50^(@) . The deviation of the ray is

When light is incident on a medium at angle i and refracted into a second medium at an angle r, the graph of sin r versus sin i is as shown. From this one can conclude that (i) the velocity of light in second medium is sqrt3 times the velocity of light in the first medium (ii) the velocity of light in the first medium is sqrt3 times the velocity of ligth in second medium (iii) the critical angle of the two media is given by sin i_C=1sqrt3 (iv) the critical anlge of the two media is given by sin i_C=1sqrt2
