Final answer:
The law of reflection states that the angle of reflection equals the angle of incidence, which means the angle light comes in at is equal to the angle it bounces off at. This law can be confirmed through experiments and is applicable to various situations.
Step-by-step explanation:
The law of reflection states that the angle of reflection equals the angle of incidence. This means that when light hits a surface and reflects off of it, the angle it comes in at will be equal to the angle it bounces off at. For example, if light hits a mirror at a 30-degree angle, it will bounce off at a 30-degree angle.
This law is confirmed through experiments where light is shone at different surfaces and the angles of incidence and reflection are measured. It is applicable to a variety of situations, such as when we look into a mirror or when telescopes use reflection to form images of stars.
Understanding the law of reflection is important in physics and optics, as it helps explain how light behaves and how we can predict the paths of reflected light.
