Question

experimentally verify laws of reflection and refraction.​

Answer 1

Explanation:

(i) The incident ray, the reflected ray and the normal at the point of incidence, lie in the same plane.

(ii) The angle of incidence and angle of reflection are equal.

i.e. ∠i = ∠r. Take a wooden drawing board and fix a white sheet of paper on it. In the middle of paper draw a straight line KK\ Mark a point B on it.
