Mirrors are reflective surfaces that allow us to see our own image. They are typically made of glass coated with a thin layer of metal, such as silver or aluminum, which reflects light. Mirrors come in various shapes and sizes, from small handheld versions to large wall-mounted types. They are commonly used in homes, bathrooms, and vehicles. In addition to personal use, mirrors have practical applications in science and technology. For example, they are essential in telescopes, where they help gather and focus light from distant objects in space. Mirrors are also used in cameras and lasers, playing a crucial role in various optical devices.
