# How to Calculate and Solve for Velocity of Light in Medium | Optical Properties

The velocity of light in medium is illustrated by the image below. To calculate the velocity of light in medium, two essential parameters are needed and these parameters are Electric Permittivity of Medium (Îµ) and Magnetic Permittivity of Medium (Î¼).

### The formula for calculating velocity of light in medium:

v =Â 1/âˆš(ÎµÎ¼)

Where:

v = Velocity of Light in Medium
Îµ = Electric Permittivity of Medium
Î¼ = Magnetic Permittivity of Medium

Given an example;
Find the velocity of light in medium when the electric permittivity of medium is 22 and the magnetic permittivity of medium is 11.

This implies that;

Îµ = Electric Permittivity of Medium = 22
Î¼ = Magnetic Permittivity of Medium = 11

v =Â 1/âˆš(ÎµÎ¼)
v =Â 1/âˆš((22)(11))
That is, v = 1/âˆš(242)
v =Â 1/15.556
v = 0.0642

Therefore, theÂ velocity of light in mediumÂ isÂ 0.0642m/s.
