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 principle applies to all reflective surfaces, including mirrors, and is fundamental to the behavior of light. When a ray of light strikes a reflective surface, the angle formed between the incoming light ray and the normal (an imaginary line perpendicular to the surface at the point of incidence) is the angle of incidence. Similarly, the angle formed between the reflected light ray and the normal is the angle of reflection. According to the law, these two angles will always be equal, allowing us to predict the path of the light after it reflects off the surface.

This relationship allows for various applications in optics, such as understanding how periscopes work or analyzing the behavior of light in optical instruments. The correctness of this statement is also reinforced by thousands of experiments and practical observations.

In contrast, other options would suggest inaccuracies about the nature of light reflection. For instance, one option incorrectly claims that the angle of incidence is greater than the angle of reflection, which does not align with experimental observations. Similarly, claiming that light does not reflect at all contradicts fundamental optical principles, and stating that the angle of reflection is twice the angle of incidence presents a relationship that does not hold true
