Answer» <p>We know that velocity of light in amedium is inversely proportional to the refractive index of the medium from the equation</p><p> n = c / v .............(1)</p><p>Moreover the refractive index of the medium is inversely proportional to the angle of refraction for the same angle of incidence from the equation</p><p> n = sin i / sin r ..............(2)</p><p>From (1) and (2) ,it is clear that velociy of light in a medium is directly proportional to the angle of refraction in that medium at a particular angle of incidence.</p><p>Thus the velocity of light is minimum inmedium A where the angle of refraction is minimum.</p>
