Question

For the same angle of incidence in media L, M and N, the angles of refraction and 45".35" and 15 respectively. In which medium will the velocity of light be minimum ? Give reason for answer​

Answer 1

Speed of light is faster in rarer medium so, for the medium r, the value of refractive index will be large and speed of the light minimum. The refractive index is small in p medium. Hence p is rarest medium so the speed of light maximum.
