Question

If the speed of light in vacuum is 3x10⁸ m/s, In other medium speed of light in a medium is 2x10⁸ so what the reflection of light??

Answer 1

This question asks us to consider the relationship between velocity and index of refraction of a medium. If we think back to the definition of index of refraction, we know that it is defined by the ratio of the velocity of light in a vacuum and the velocity of light in some other medium.

n=cv

n is the index of refraction, c is the speed of light in a vacuum, and v is the speed of light in the new medium.

n=3.0 x 10^8/2.0 x 10^8

n=0.5

index of refraction n=0.5

Answer 2

Explanation:

the answer is 0.5
