What are the reflectors of light?

Reflectors of light are surfaces that bounce light rays back, allowing them to change direction without absorbing much energy. Common examples include mirrors, which have a smooth, shiny surface that reflects light effectively, and polished metals, which can also reflect light due to their smoothness. The angle at which light strikes the surface determines the angle at which it reflects, following the law of reflection. Reflective materials are used in various applications, from optical devices to safety signs.
