How can you see an image in a mirror?

You can see an image in a mirror because mirrors reflect light. When light from an object strikes the mirror's surface, it bounces off at the same angle it hit, allowing your eyes to receive the reflected light. This creates a reversed image of the object, which you perceive as a reflection in the mirror. The smooth, shiny surface of the mirror enhances this reflection, making it possible for you to see a clear image.
