Speed of light in a medium depends on

inertial properties of the medium

elastic properties of the medium

inertial as well as elastic properties of the medium

neither inertial nor elastic properties of the medium

Text Solution

Verified by Experts

The correct Answer is:

We should know that speed of light in vacuum is a constant and speed of light in a medium depends only on electrical and magnetic properties of the medium. Elastic and inertial properties of the medium has no influence on speed of light. These properties affect speed of mechanical waves not of non-mechanical waves.
