Question

The refractive index of a medium 'X' with respect to a medium y' is 2/3
and the refractive index of medium y with respect to medium *' is 4/3
Find the refractive index of medium Y with respect to medium . If the
speed of light in medium * 3 * 10" ma calculate the speed of light
in medium y​

Answer 1

Explanation:

answer is 9 by 8

Answer 2

the refractive index of medium y with respect to medium X is 9/8

the speed of light in medium y is 2×10^8 m/s
