Question

2 laws of refraction​

Answer 1

Explanation:

Snell's law is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.

Answer 2

Answer:LAWS OF REFRACTION

Explanation:

THE TWO LAWS OF REFRACTION ARE: 1) THE RATIO OF SINE OF ANGLE OF INCIDENCE IS EQUAL TO THE SINE OF ANGLE OF REFRACTION WHERE IT IS CONSTANT FOR A GIVEN PAIR OF MEDIA.... 2) THE INCIDENT RAY, THE REFRACTED RAY, AND THE NORMAL LIE ON THE SAME PLANE..
