Question

State Shell's law of refraction?​

Answer 1

Explanation:

The ratio of sine of angle of incidence to the sine of angle of refraction is a constant, for the light of a given color and for the given pair of media. This law is also known as Snell's law of refraction. This constant is also called the refractive index of the second medium with respect to the first.

Answer 2

Answer:

Snell's law (also known as Snell–Descartes law and the law of refraction) is a formula used to describe the relationship between the angles of incidence and refraction, when referring to light or other waves passing through a boundary between two different isotropic media, such as water, glass, or air.

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
