Description: Have you ever wondered how binoculars and telescopes allow us to see far beyond what our eyes allow? Learn what diverging lenses are and how they affect light.

Question

Separate the given diagrams as no deviation, deviation towards normal and deviation away from normal.

Accepted Answer

No deviation takes place in the case of a light ray falling normally on a medium. (c) and (e)

When light is incident obliquely, from a medium of higher optical density to a medium of lower optical density, the refracted ray deviates away from the normal. (b) and (d)

When light is incident obliquely, from a medium of lower optical density to a medium of greater optical density, the refracted ray deviates towards the normal. (a)

The optical density is an important factor for the refraction of light and it is directly related to the refractive index of the material. The refractive index is defined as the ratio of the speed of light in air or vacuum to the speed of light in that medium.
