Mirrors are smooth surfaces that reflect light, allowing us to see our own image. They are commonly made of glass with a shiny coating, often silver or aluminum, on the back. People use mirrors in various places, such as bathrooms, dressing rooms, and even in cars to check their appearance or surroundings. In addition to personal use, mirrors have fascinating applications in science and technology. For example, they are essential in telescopes, helping astronomers observe distant stars and galaxies. Mirrors also play a role in art, where artists like Pablo Picasso have used reflections to create unique perspectives in their work.
