Question

For the same angle of incidence, the angle of refraction in

three different media A, B and C are 10°, 25° and 40°
respectively. In which medium the velocity of light will be
maximum?
​

Answer 1

Media C

Step-by-step 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.
