What does the law of reflection state?

The law of reflection states that the angle of incidence is equal to the angle of reflection. This fundamental principle of optics applies to all reflective surfaces, including mirrors. When a ray of light strikes a reflective surface, the angle at which it approaches the surface, known as the angle of incidence, is always equal to the angle at which it bounces off, referred to as the angle of reflection. This equal relationship holds true regardless of the specifics of the reflective surface, ensuring consistent behavior of light when it interacts with reflective materials. Understanding this law is crucial for analyzing various optical systems and applications, such as designing mirrors and optical instruments.
