Question

Define refractive index using speed of light...

Answer 1

Answer:

The refractive index of a substance is a measure of the amount of bending after a boundary.

It is calculated using this equation: refractive index = speed of light in a vacuum/speed of light in the medium.

• The speed of light in a vacuum is 300 000 000 m/s (3 × 108 m/s).

Answer 2

Answer:

refractive index of an medium is the ratio of speed of light in vacuum to speed of light in that medium

Explanation:

n=c/v

here c=speed of light in vacuum

v= speed of light in that medium
