An example of light being reflected is:

• A. A window
• B. A mirror
• C. A piece of wood
• D. A clear bottle

Answer: (B)

Light reflection occurs when light bounces off a surface. A mirror is specifically designed to reflect light; it has a smooth surface that allows light rays to maintain their angle as they bounce off. This makes mirrors effective for creating clear images because they reflect nearly all the light that hits them, allowing you to see your reflection vividly.

In contrast, while a window can also reflect light, it is primarily designed to allow light to pass through, which makes its reflective properties less pronounced. Similarly, a piece of wood and a clear bottle do not effectively reflect light like a mirror does. The clarity and smoothness of a mirror's surface are what enable it to provide a clear reflection, distinguishing it as the best example of light being reflected.
