Question

the speed of light in medium of refractive index n is _______
,where c is the speed of light in vacuum.​

Answer 1

Explanation:

= c / v" "c" is the speed of light in a vacuum, "v" is the speed of light in that substance and "n" is the index of refraction. According to the formula, the index of refraction is the relation between the speed of light in a vacuum and the speed of light in a substance.

Answer 2

Answer: It is c/n

Explanation:

We know refractive index(n) = speed of light in vacuum(C)/ speed of light in medium..

Therefore, speed of light in medium will be c/n
