Question

for the same angle of incidence in media A,B and C and the angle reflections are 20 degree , 30 degree and 40 degree respectively. in which angle the velocity of light be maximum? give reason in support of your answer​

Answer 1

Answer:

ANSWER

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.
