Final answer:
The law of reflection states that the angle of reflection is equal to the angle of incidence. Light reflects off smooth surfaces at specific angles, while light reflects off rough surfaces in multiple directions.
Step-by-step explanation:
The law of reflection states that the angle of reflection is equal to the angle of incidence. This means that when light hits a smooth surface, it will bounce off at the same angle that it hit the surface. In contrast, when light reflects from a rough surface, it is diffused and reflected in many different directions.
