Question

For the same angle of incidence the angle of refraction in three different media a, b, c are 10 degree 15 degree 20 degree respectively in which medium is the speed of light minimum and in which medium is the speed of light is maximum

Answer 1

Explanation:

We know that ratio of sine of angle of incidence to the sine of refraction gives refractive index. Increases in refractive index increases the range of bending. Here angle of incidence is same in every case. The angle of refraction is greater in c. It has less refractive index and hence, light suffer less bending, which increases its speed
