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 10^8 ms-1, calculate the speed of ligh
in medium ‘y'​
