What does the law of reflection state about angles?

The law of reflection states that the angle of incidence is equal to the angle of reflection when a wave, such as light, strikes a reflective surface. This principle is fundamental in optics and can be observed when light bounces off mirrors or any other reflective surface.

When light hits a surface, the angle that the incoming light makes with a perpendicular line to the surface (known as the normal line) is termed the angle of incidence. The angle at which the light reflects away from the surface, measured the same way with respect to the normal line, is called the angle of reflection. According to the law of reflection, these two angles are identical, meaning they have the same measure, which is crucial for understanding how light behaves in various scenarios, including in the design of optical instruments and understanding phenomena such as the mirage effect.

The other options propose different relationships between the angles, which do not align with the established laws of physics governing reflection. Understanding the equality of these angles is essential in fields such as physics, engineering, and various applications in technology involving light.
