Question

what are the laws of refraction​

Answer 1

Answer:

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. This is also known as Snell's law of refraction.

Answer 2

Answer:

1. Incident ray, reflected ray and the normal all lie in same plane.

2. Ratio of Sine of angle of incidence and Sine of angle of reflection is unity.

$\sin( \alpha ) \div \cos( \alpha ) = 1$
