Calculate the speed of light in a medium whose refractive index is 2.4

Approximately .

Explanation:

Look up the speed of light in vacuum: . Denote the speed as .

If the speed of light in a medium is , the refractive index of that medium would be:

.

Note, that the refractive index of a medium is inversely proportional to the speed of light in this medium. A medium with a larger refractive index would thus correspond to a slower speed of light.

Rearrange this equation to find the speed of light in this medium:

.
