Question

7. What is refraction. Explain its laws with diagram.​

Answer 1

The law of refraction, or Snell's law, predicts the angle at which a light ray will bend, or refract, as it passes from one medium to another. Encyclopædia Britannica, Inc. By definition, the index of refraction for a vacuum is exactly Light rays passing through a lens are bent at both surfaces of the lens.

Answer 2

Answer:

the bending of light when it enters front one medium to another is refraction.

The 2 laws of refraction are

1. when sine of angle of incidence is equal to the sine of angle of refraction provided temperature and pressure remains constant. this is also called as snells law
2. the angle of incidence at the interface of the 2 transparent media is equal to the angle of refraction
