Light of higher frequency has a greater refractive index than lower frequency light. This explains why a prism can disperse white light into different colours. The change in refraction is quite ...

It is then refracted away from the normal at the boundary between glass and air as it leaves the prism.

WHEN a pencil of light proceeding from a luminous point is incident upon a prism, the rays after refraction do not as a rule diverge from a point, but from two short lines at right angles to each ...
