Question

For the same angle of incidence, the angles of refraction in three different media A,B,C are 15°,25,35
respectively. In which medium will the velocity of light be minimum Give reason to support your
answer​

Answer 1

Answer:

We know that the refractive index = sin I/ sin R and here in this case sin I is constant for all three given conditions as incidence angle is same

Now the least refracting angle will have least value of sin R thus will have highest refractive index

We know that lights velocity is lees in medium with high refractive index thus 15° is the answer
