Question

Defined Snell's law ​

Answer 1

Answer:

a law stating that the ratio of sites of the angles of incidence and refractions of a wave are constant when it passes between two given media.

Explanation:

snell's law , in optics , a relationship between the path taken by a ray of light in crossing the boundary or surface of separation between two contacting substances and the refractive index of each. .... snell's law asserts that n1/n2 = sin a2/ sina1

hope this ans may help you .

thankyou

Answer 2

Snell's law is defined as the ratio of the sine of angle of incidence to the sine of the angle of refraction which is constant for a given pair of media and it is also known also as refractive index of the medium.
