What would occur if the index of refraction of a material was less than n=1?

The speed of light would increase to a speed larger than the maximum speed of light in a vacuum.
The light wave would not bend at all though the material.
The light wave would not be able to refract and would instead reflect off of the material.
The speed of light would reduce to values close to 0 m/s.

Respuesta :

The correct answer is (A). The speed of light would increase to a speed larger than the maximum speed of light in vacuum.

The index of refraction is the ratio of speed of light in vacuum to the speed of light in a medium.

n=C/V

here, n is the index of refraction, c the speed of light in vacuum, v is speed of light in any medium.

Now if the value of index of refraction is less than one, than the value of speed of light would be greater than the speed of light in the vacuum.
