# Solution - The velocity of light in a medium is 1.5 x 108 m/s. What is the refractive index of the medium with respect to air, if the velocity in air is 3 x 108 m/s? - SSC (Marathi Semi-English) 10th - Science and Technology - 1

#### Question

The velocity of light in a medium is 1.5 x 108 m/s. What is the refractive index of the medium with respect to air, if the velocity in air is 3 x 108 m/s?

#### Solution

Given that

v_1=3xx10^8

v_2=1.5xx10^8

We know that, the refractive index with respect to air is

n=v_1/v_2

therefore n=(3xx10^8)/(1.5xx10^8)

Thus, the refractive index of the medium with respect to air is 2.

Is there an error in this question or solution?
