What does the Law of Reflectance state?

The Law of Reflectance states that the angle of incidence equals the angle of reflection. This principle indicates that when a wave, such as light, strikes a reflective surface, the angle at which it hits the surface (the angle of incidence) is precisely matched by the angle at which it reflects away from the surface (the angle of reflection). This relationship can be observed in everyday situations, such as when light reflects off a mirror.

Understanding this law is fundamental in physics, particularly in the study of optics, because it describes how light behaves in various scenarios, such as reflections on mirrors, water surfaces, and other reflective materials. This principle is crucial for applications involving vision and design in technology, such as in the creation of optical devices.
