Answer 2

Answer:

Given:

Refractive index:

▪ x/y = 2/3 ...(1)

▪ y/z = 4/3 ....(2)

Take out the value of x from (1):

x = 2y/3

Take out the value of z from (2):

z = 3y/4

Ratio to find:

z/x = 3y/4 × 3/2y

= 9/8

---

Speed of light in medium x = 3 × 10^8 m/s

=> x/y = 2/3 = 3 × 10^8/y

=> 9 × 10^8/2 = y

=> 4.5 × 10^8 m/s = y
