If velocity of light in the air is

C

then what will be the velocity of light in medium of refractive index 1.4?

View answer and explanation

Correct option: A

2.1 \times 10^8 \mathrm{~m} / \mathrm{s}

Option A (

2.1 \times 10^8 \mathrm{~m} / \mathrm{s}

) is correct because the velocity of light in a medium is the speed of light in vacuum divided by the refractive index of the medium.
