Question

What are laws of refraction ?​

Answer 1

$\mathtt{\huge{ \fbox{ Answer :)}}}$

The bending of light rays when it passes through one medium to another medium is called refraction of light

Law's of refraction :

i) The incident ray , refracted ray and normal at a point of incidence all in the same plane

ii) The ratio of sin of angle of incidence to the sin of angle of refraction is constant for a given pair of medium

It can be mathematically written as ,

$\large \mathtt{ \fbox{ \frac{\sin \: (i) }{ \sin \: (r) } = constant }}$

The second law of refraction is also known as Snell's law of refraction

Answer 2

Answer:

the principle that when a ray of light, radar pulse, or the like, is reflected from a smooth surface the angle of reflection is equal to the angle of incidence, and the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane.
