Question

Explain snell's law................​

Answer 1

Answer

The snell's law states that the ratio of sine of angle of incidence to the sine of angle of refraction is always constant for two reasons. →μ(constant) = refractive index = sinisinr.

Answer 2

Answer:

Snell's law (also known as Snell–Descartes lawand the law of refraction) 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.
