Question

The refractive index of crown glass is 1.52 what does this mean

Answer 1

Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. ... The equation n = c/v in this case indicates, correctly, that the velocity of X-rays in glass and in other materials is greater than its velocity in empty space

Answer 2

Answer:

The refractive index of crown glass is 1.52. This means that light travels in air 1.52 times faster than it does in crown glass.
