Question

Velocity of light in air is 3 x108m/s.While its velocity in a medium is 1.5x108m/s. Then, refractive index of

this medium is

a. 3 b. 5 c. 0.5 d. 2
​

Answer 1

Answer:

OPTION D. REFRACTIVE INDEX IS 2

Explanation:

GIVEN IN PIC

Answer 2

Answer:

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

Explanation:

Refractive Index = v1/v2

Refractive Index = 3*10^8/1.5*10^8

Refractive Index = 2
