Question

What is the snell law? ( Class 10 | Ch - Light )
Write the formula of shell law
Also state it ​

Answer 1

Answer:

Snell's law asserts that n1/n2 = sin α2/sin α1. Overview of optics and light refraction. 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

Answer:

Definition: Snell's law is defined as “The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, for the light of a given colour and for the given pair of media".

Formula:

n_1 \sin \theta_1 = n_2 \sin \theta_2

n_1 \sin \theta_1 = n_2 \sin \theta_2n_1 = incident index

n_1 \sin \theta_1 = n_2 \sin \theta_2n_1 = incident indexn_2 = refracted index

n_1 \sin \theta_1 = n_2 \sin \theta_2n_1 = incident indexn_2 = refracted index\theta_1 = incident angle

n_1 \sin \theta_1 = n_2 \sin \theta_2n_1 = incident indexn_2 = refracted index\theta_1 = incident angle\theta_2 = refracted angle
