Understanding the phenomenon behind a mirror and what makes it a reflecting substance is necessary to comprehend the concept of a mirror. The law of reflection, which states that when a ray of light is made to fall on a reflecting surface, the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane and the angle of incidence is equal to the angle of reflection, can be used to define a mirror as a reflecting surface.

Terms Concerning Mirrors

• Incident ray: A beam of light that strikes the surface is what it is called.

• Reflected ray: The term "reflected ray" refers to a light beam that, after striking a surface, reflects again.

• Normal ray: The term "normal ray" refers to a ray that is perpendicular to or at 90 degrees to a reflecting surface.

• Refracted ray: This term refers to an incident ray that changes direction after passing through a second medium.

• Angle of incidence: This term refers to the angle formed by the incident beam and its corresponding normal.
