A plane mirror is a flat, reflective surface that produces clear images of objects placed in front of it. It reflects light rays according to the law of reflection, where the angle of incidence equals the angle of reflection. This type of mirror is commonly used in homes, bathrooms, and vehicles for personal grooming and safety. When you look into a plane mirror, you see a virtual image that appears to be the same size as the object. The image is reversed from left to right, which is why text appears backward. Plane mirrors are essential in various applications, including optics, cameras, and periscopes.
