Question

Explain Snell's law.
________________​

Answer 1

Answer:

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. This law was discovered in 1621 by the Dutch astronomer and mathematician Willebrord Snell.

Formula

n_1 \sin \theta_1 = n_2 \sin \theta_2

n_1 = incident index

n_2 = refracted index

\theta_1 = incident angle

\theta_2 = refracted angle
