Here's a breakdown:
* Incident ray: The ray of light that strikes the mirror.
* Reflected ray: The ray of light that bounces off the mirror.
* Normal: An imaginary line perpendicular to the mirror's surface at the point where the incident ray hits.
The angle between the incident ray and the normal is called the angle of incidence, and the angle between the reflected ray and the normal is called the angle of reflection. The law of reflection states that the angle of incidence is equal to the angle of reflection.
