Problem 3CQ

Why is the index of refraction always greater than or equal to 1?

Step-by-Step Solution:
Step 1 of 3

Solution 3CQ

Index of refraction of material can be defined as

n = Here, n, c, v is respectively, refractive index of the medium in which light travels, speed of light in the medium and speed of light in vacuum.

Since speed of light is maximum in vacuum and always less than c in any other medium/material, therefore from equation of refractive index value of index of refraction of any medium is equal to or greater than 1.

Hence, n Step 2 of 3

Step 3 of 3
