Here's a breakdown:
* Angle of incidence: The angle between the incoming light ray (the incident ray) and the normal (a line perpendicular to the surface at the point of incidence).
* Angle of reflection: The angle between the reflected light ray and the normal.
The Law of Reflection: The angle of incidence is always equal to the angle of reflection.
This principle applies to both smooth and rough surfaces.
Example: Imagine a mirror. If you shine a light ray at an angle of 30 degrees to the mirror's surface, the reflected ray will also be at an angle of 30 degrees to the surface, but on the opposite side of the normal.
