Reflective surfaces are materials that bounce back light, allowing us to see images or colors. Common examples include mirrors, water, and polished metals. These surfaces can create clear reflections, which are useful in various applications, from personal grooming to architectural design. The effectiveness of a reflective surface depends on its smoothness and material properties. For instance, a mirror has a highly polished surface that provides a clear reflection, while a rough surface, like sandpaper, scatters light and produces a blurry image. Understanding how these surfaces work is essential in fields like photography and optics.
