Reflection is a common wave phenomenon in physics. It is the phenomenon according to which a ray of light deviates from its path, when it strikes a surface separating two media. In wave propagation theory, reflection takes place when an electromagnetic wave impinges an object having larger dimensions than the wavelength of the propagating wave. It occurs from the walls of the buildings, trees etc. In general language, reflection refers to a simple mirror image in a mirror or water having the same dimensions as the object. Reflection may also used to refer to retrospection which means giving a thought to matters concerning self. In the words of Frederick Douglass, “A battle lost or won is easily described, understood, and appreciated, but the moral growth of a great nation requires reflection, as well as observation, to appreciate it.”
