The laws of reflection hold true for :(a) plane mirrors only (b) concave mirrors only(c) convex mirrors only (d) all reflecting surfaces

(d) all reflecting surfaces

Explanation

The laws of reflection hold true for all the reflecting surfaces, i.e all mirrors (either plane or spherical) regardless of their shape.

Laws of Reflection 

The ray of light that approaches the mirror is known as “Incident Ray”. The ray that bounces back is called the "Reflected Ray". At the point of incidence where the incident ray strikes the mirror, a perpendicular line is drawn called the “Normal”.

The law of reflection states that-

(i) The incident ray, the reflected ray and the normal all lie in the same plane.

(ii) The angle of incidence = Angle of reflection.
