Question

what is the law of reflection and refraction

Answer 1

Explanation:

Law of reflection:

1)angel of incidence (i) = angel of

reflection (r)

2)the incident ray, the refracted ray and the normal to the surface lie in one plane.

Law of refraction:

1)The incident ray , the refracted ray and the normal to the surface lie in the same plane .

2) the ratio of sin of angel of incidence to the sin of angel of reflection is constant for a given pair of medium.

Answer 2

Answer࿐

Laws of reflection:-

1st law:-The incident ray, the reflected ray,and the normal at the point of incidence lie on the same plane.

2nd law:- The angle of incidence is equal to the angle of reflection.
