According to the law of reflection, what is true about the angle of incidence?

The law of reflection states that when a ray of light (or any wave) strikes a reflective surface, the angle at which it arrives, known as the angle of incidence, is precisely equal to the angle at which it is reflected away from that surface, known as the angle of reflection. This principle is fundamental in optics and applies to all types of waves, including sound and light.

This equality between the angle of incidence and the angle of reflection is crucial for understanding phenomena such as the behavior of light in mirrors, as well as other applications in fields like surveying and engineering. The concept is not only mathematically significant but also has practical implications in designing optical systems, such as telescopes and cameras, where accurate reflection angles are necessary for proper functioning. Thus, the relationship established by the law of reflection asserts the balance and symmetry inherent in wave behavior upon encountering reflective surfaces.
