If the speed of light is 1.5times that of the speed of light in a given material what is the index of refraction for that material

Respuesta :

The answer is 1.5....
The refractive index n = (Speed of light, c) /( Speed of light, v)
So c= n x v
comparing to c= 1.5 x v in this situation we see that n= 1.5
