Question

formula for snell law

Answer 1

Answer:

Snell's law asserts that n1/n2 = sin α2/sin α1. Because the ratio n1/n2 is a constant for any given wavelength of light, the ratio of the two sines is also a constant for any angle.

Answer 2

Explanation:

i think here i is angle of incidence and r is angle of refraction

sin i/sin r=constant
