Question

if refractive index of medium 2 with respect to medium 1 is n21,then the refractive index of the medium 1 with respect to medium 2 is

Answer 1

Answer:

Thus, to calculate the refractive Index the speed of light in two media is taken. Above expression gives the refractive index of medium 2 with respect to medium 1. This is generally denoted by n21. Similarly, the refractive index of medium 1 with respect to medium 2 is denoted by n12.
