Question

Light travelling
travelling in a medium with velocity 3× 108 m/
in refracted into the second medium in which it
travels with velocity 2x108 m/s what is the
refractive index
the second medium ? - (1M)​

Answer 1

Answer:

Correct option is

C

2

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.

Answer 2

Answer is 3/2
