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 zis 4/3.
Find the refractive index of medium 'Z' with respect to medium 'x'. If the
speed of light in medium 'x' is 3 x 108 ms-1, calculate the speed of light
in medium 'y'.​

Answer 1

Answer:

the refractive index of medium z with respect x =9/8

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