Question

The speed of light in an unknown medium is measured to be 2.76 x 108 m/s. What is the index of refraction of the medium

Answer 1

Answer:

The index of refraction, n, is the ratio of the speed of light in a vacuum, c, to the speed of light in a medium, c': One consequence of this difference in speed is that when light goes from one medium to another at an angle, the propagation vector in the new medium has a different angle with respect to the normal.

Explanation:

Answer 2

Answer:

The speed of light in a medium is v=cn v = c n , where n is its index of refraction. If we divide both sides of equation c = fλ by n, we get cn=v=fλn c n = v = f λ n .
