Question

Show that the refractive index of a medium 1 with respect to medium 2 is reciprocal to the refractive index of medium 2 with respect to lie. n12 1/ n21

Answer 1

v1=medium two
v=medium one

Answer 2

Answer:

ANSWER

Refractive index of a medium =

Speed of light in that medium

Speed of light in vacuum

The refractive index of medium 2 with respect to medium 1 is given by the ratio of the speed of light in medium 1 and the speed of light in medium 2.

Refractive index of medium 2 with respect to medium 1=

Speed of light i medium 2

Speed of light in medium 1
