Question

Explain the significance of second law of refraction

Answer 1

Answer:

The second law of refraction states that the ratio of sine of angle of incidence to the sign of angle of refraction is constant to the interface of any two given medium. The second law is also called Snell's law

Answer 2

According to second Law of refraction, ratio of the sine of angle of incidence i to the sine of angle of refraction r is always constant for a given wavelength of light.

Where Incident ray, coming from one medium to the boundary of another medium, gets refracted, this constant is the refractive index of second medium relative to the first medium.

This can be written as:

$\frac{Sin\:i}{Sin\:r}$ = constant is known as Snell's law.
