3. The absolute refractive index of a transparent medium is 2.4 and the speed of light
in that medium is 1.25 x 108 m/s. Find the speed of light in air.​

Answer 1

Explanation:

The speed of light in a transparent medium is given as 2.4×108ms−1. Calculate the absolute refractive index of the medium. A. 1.5 ... It is given by the equation, n=cv ... n=3×108 2.4×108

Answer 2

Answer:

The refraction index, n, of a transparent medium is defined as the ratio of speed of light in vacuum to the speed of light in that medium. The formula is n= vc

.

where the speed of light c=3×10 8

m/s and v is the speed of light in the desired medium which is given as v=2.4×10

8

m/s.

Therefore, n= 2.4×10 8 m/s

3×10 8m/s =1.25.

Hence, the refractive index of the transparent medium is 1.25.
