This scenario describes the behavior of light known as "reflection." When parallel light waves encounter a smooth surface, they bounce off in a predictable manner, following the law of reflection. The angle of incidence (the angle at which the light wave approaches the surface) is equal to the angle of reflection (the angle at which the light wave bounces off the surface). This phenomenon is fundamental in optics and is observed in everyday situations, such as looking at your reflection in a mirror.
Therefore, the correct behavior of light described in this scenario is:
- Reflection
