Question

The bending of light on passing from one medium into another is called _____________.

Answer 1

Refraction- A change in direction generated by a wave's speed when it travels from one medium to another.

1. The difference in density between the two substances causes bending.
2. Refraction of light is one of the most often observed phenomena, but it also occurs in other waves like sound and water. Because of refraction, we use optical equipment like magnifying glasses, lenses, and prisms.
3. We also focus light on our retina due to light refraction.
4. Thus, the bending of light on passing from one medium into another is called refraction.
