Mention two laws of refraction .​

Answer 1

Answer:

Question:-

Mention two laws of refraction.?

Answer:-

• The incident ray refracted ray, and the normal all lie on the same plane.
• angle of incidence = angle of reflection

hope this helps.!

Answer 2

Answer:

1) Incident ray and refracted ray at the point is incidence N are on the opposite sides of the of the normal to the surface of the slab at the point i.e. CD, and the three, incident ray, refracted ray and the normal,are in the same plane.

2)For a given pair of media,here air glass the ratio of sin i to sin r is aa constant. Here,i is the angle of incidence and r is the angle of refraction.

sin i = contant= n

sin r

where n is called the refractive index.Also this second law is called as Snell's law.
