Question

The speed of light in a transparent medium is 2.4 × 10×10 8 times . calculate absolute refractive index of the medium.

Answer 1

Thus the refractive index of the medium is 1.25

Explanation:

The formula of refractive index is n=   c / v ​

Where c =  the speed of light = 3×10^8  m/s

V = the speed of light in the desired medium

V = 2.4×10^8   m/s

n = 3×10^8   / 2 x 10^8 m/s

n = 1.25

Thus the refractive index of the medium is 1.25

Answer 2

Answer:

3×10 raise to the power 8m/s
