A mirror is a reflective surface, typically made of glass, that has a thin layer of metal on one side. This coating allows it to reflect light, creating a clear image of whatever is in front of it. Mirrors are commonly used in homes, bathrooms, and vehicles, serving both practical and decorative purposes. Mirrors come in various shapes and sizes, from small hand-held versions to large wall-mounted designs. They can also be found in different types, such as convex mirrors, which curve outward and provide a wider field of view, and concave mirrors, which curve inward and can magnify images.
