''REFRACTION OCCURS THROUGH GLASS SLAB''WHY?

GIVE A SCIENTIFIC REASON

Answer 1

Answer:

Causes of refraction

Light travels in different speed in different mediums. For example light travels faster in air than in a glass. Therefore, it is due to the change of speed of light in different medium that the light rays are refracted.

Optically rarer medium

A transparent substance (medium) in which the speed of light is more is called optically rarer medium.

Optically denser medium

A transparent substance (medium) in which the speed of light is less is known as optically denser medium.

Glass is an optically denser medium than air and water.

Hope it helped..
