Question

Define reflection. State the two laws of reflection.

Answer 1

Answer:

REFLECTION :-

Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated.

TWO LAWS OF REFLECTION :-

(•) The incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane.

(•) The angle of incidence i = the angle of reflection r.Both angles are measured with respect to the normal to the mirror.

Answer 2

reflection is the process of bounce back of wave wheather it is light or sound to the same medium from which it have came to the reflecting surface

Explanation:

the two laws of reflection are

1 . the parallel beam of light is parallel after reflection if the reflecting surface is smooth

2. light Ray's fall at different points on a rough surface each day get reflected from it obeying at different points
