Question

Explain the three laws of Refraction ?
​

Answer 1

Answer:

Laws of refraction state that: The incident ray, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane. The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant.

Answer 2

Answer:

The first law of refraction states that the incident ray, refracted ray and the normal all lie in the same plane.

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.

The this law of refraction states that the angle of incidence is always equal to the angle of reflection, that is, Angle i = Angle r.
