What are the two laws of reflection?

Incident Ray: The light ray, which strikes any surface, is called the incident ray.

Reflected Ray: The ray that comes back from the surface after reflection is known as the reflected ray.

Normal: A line drawn perpendicular to the line representing the mirror at the point where the incident ray strikes the mirror.

Angle of incidence: The angle between the normal and the incident ray is called the angle of incidence. It is denoted as i.

Angle of reflection: The angle between the normal and the reflected ray is called the angle of reflection. It is denoted as r.

Laws of reflection.

First law of reflection: According to the first law, the incident ray, reflected ray, and normal ray, all lie in the same plane.

Second law of reflection: According to the second law, the angle of reflection is always equal to the angle of incidence.

(∠i = ∠r)
