Question

The refractive indices of medium 1,2 and 3 are 1.76,1.85, 1.92 respectively. State in which medium speed of light will be minimum and in which medium speed of light will be maximum? State reasons for your answer.

Answer 1

Answer:

Minimum: Medium 3

Maximum: Medium 1

Explaination:

The refractive index of a medium means the ability of a given medium to bend the light.

So according to this medium 3 bends the light more so the speed will be minimum and medium 1 has lower refractive index and hence it bends the light less therefore the speed of light will be maximum.

Hope it helps.
