Question

write about Snell's law
​

Answer 1

Answer:

Snell's law (also known as Snell–Descartes law and 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.

Answer 2

Answer:

The laws of refraction or Snell's laws (class 10) states: For a given pair of media, the sine value of the angle of incidence (denoted by sin i) divided by the sine value of the angle of refraction (denoted by sin r) is constant, which is known as the refractive index of the medium.
