Which statement is true about the law of reflection?
Leya [2.2K]

Answer:

The law of reflection defines that upon reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray, with respect to the normal to the surface that is to a line perpendicular to the surface at the point of contact.

The reflected ray is always in the plane defined by the incident ray and the normal to the surface at the point of contact of the incident ray.

The images produced by plane mirrors and curved mirrors can be understood by the law of reflection.

Law of reflection is defined as:

The principle when the light rays falls on the smooth surface, the angle of reflection is equal to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.
