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 ʻz is 4/3.
Find the refractive index of medium ‘z with respect to medium 'Y'. If the
speed of light in medium *x' is 3 x 10^8ms-1, calculate the speed of light
in medium 'y'.​

Answer 1

Answer:

Explanation:

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
