Comparison of specular reflection from a smooth surface and diffuse reflection from a rough surface.
A narrow beam of parallel light rays is directed onto a smooth, polished metal plate and then onto an unpolished sheet of white paper. The light reflecting from the metal plate forms a clear specular reflection, whereas the light reflecting from the paper undergoes diffuse reflection and scatters in many directions.
