Question

5. The speed of light in a medium is 1.73×10^8 m/s. Find the refractive index of the medium ​

Answer 1

Answer:

Given : Velocity of medium =1.5×108m/sec.

            Velocity of light, c=3×108m/sec.

To find : n=?

             n=vc

             n=1.5×1083×108

                =2

            n=2

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