Question

Refractive index of media A, B, C and D are A B C D 1.33 1.52 1.44 1.65 In which of the four media is the speed of light (i) maximum (ii) minimum?

Answer 1

as we know that the refractive index of the medium is inversely proportional to the velocity so the 1)maximum speed will be of 1.33
2) minimum speed will be of 1.65

Thankyou:)
