Question

State Snell's laws of refraction.​

Answer 1

Explanation:

Snell's Law states that the ratio of the angle of incidence to the angle of refraction of a wave as it travels through a boundary between two media is a constant termed the refractive index.

Answer 2

Answer:

here is u r answer.

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 etc.
