Question

State laws of refraction?

Answer 1

2 laws of refraction -

1. Incident ray, refracted ray and normal lie on the same plane.

2. The ratio b/w sine of angle of incidence to the sine of angle of refraction is always constant... 2nd law is also known as snells law

Answer 2

the ratio of angle of Sin A by sin I is equal to constant For any given media..

the incident ray the reflected ray and the normal at the point of incidence online the same plane
