Question

The refractive index of medium a,b,c and d are 1.33,1.44,1.52 and 1.65 which will have maxium and inimum speed of light and why

Answer 1

n = c/v

Clearly, n is inversely proportional to v, hence, Maximum n will have minimum v and vice versa.

Hence, maximum speed is of medium with n. = 1.33

And minimum speed is of medium with n = 1.65
