Question

the refractive index of a medium X with respect to 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 3x10 to the power 8 metre per second calculate the speed of light in medium Y​

Answer 1

Answer:

the refractive index of medium Z with respect to medium X.= 9/8

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

hope this helps you plz mark as brainliest plz....
