Question

the refractive index of medium X with respect to medium Y is 2 by 3 and the refractive index of Y with respect to medium Z is 4 by 3 find the refractive index of medium Z with respect to medium x

Answer 1

In refraction, calculation angles are depend and are measured between the rays and the normal.

It often calculates the change in direction of a ray depends on with the change in speed of the light.

This can be used to calculate refractive Index from medium Z with respect to X.

 X/Y= 2/3

Y/Z=4/3

X/Y*Y=2/3*4/3

X/Z=8/9

Z/X= 9/8

So, the refractive index of Z with respect to X is 9/8

Answer 2

Answer:

Correct Answer is 9/8
