Final answer:
When light reflects off a smooth flat surface, it bounces off at the same angle due to the law of reflection.
Step-by-step explanation:
When light reflects off a smooth flat surface, it bounces off at the same angle. This is known as the law of reflection. The angle of incidence (the angle between the incident ray and the normal to the surface) is equal to the angle of reflection (the angle between the reflected ray and the normal to the surface).
For example, if light rays coming from a flashlight hit a mirror, they will bounce back in such a way that the angle between the incoming rays and the mirror's surface equals the angle between the reflected rays and the mirror's surface.
