Question

write the formula of snell's law​

Answer 1

In the Figure, n1 and n2 represent the indices of refraction for the two media, and α1 and α2 are the angles of incidence and refraction that the ray R makes with the normal (perpendicular) line NN at the boundary. Snell's law asserts that n1/n2 = sin α2/sin α1

Answer 2

SIN I / SIN R = CONSTANT

Explanation:

or n1 sin teta1 = n2 sin teta2
