Question

What is Snell's Law, write it's formula..?

Bye piople :) ​

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.

• 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 (also called Snellius)

• The angle of incidence in the water is approximately 39°. At this angle, the light refracts out of the water into the surrounding air bending away from the normal. The angle of refraction in the air is approximately 57°. These values for the angle of incidence and refraction are consistent with Snell's Law.
