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 'z' is 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.
(i need correct answers only)​

Answer 1

Answer:

refractive index of medium z with respect to medium y is 9/8.

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