Question

Angle of incidence is equal to the angle of reflection.
(a) Always
(b) Sometimes
(c) Under special conditions
(d) Never

Answer 1

Always.Because the incident ray or wave and the reflected ray make the same angle with the normal to the surface

Answer 2

The answer to the given question is that the angle of incidence is always equal to the angle of reflection.

So the right answer is the option (a) that is always.

That is the angle of reflection and the angle of incidence are always equal.

This is called as the normal at a reflecting point of contact.

The angle that lies between the incident ray and the normal is called the angle of incidence.
