Answer 1

Answer:

a law in physics: the ratio of the sines of the angles of incidence and refraction is constant for all incidences in any given pair of media for electromagnetic waves of a definite frequency.

please mark me as brainliest answer and follow me

Answer 2

Answer:

For a given pair of media, the ratio of sine of the angle of incidence to the sine of the angle of refraction is constant.

that is, sin i/sin r = constant

This law is known as Snell's law
