Wave or Wavelength
Wave or Wavelength : A unit of relative distance equal to the length of a wave: this could be a light wave, a radio wave, or even an ordinary water wave. In communications engineering, the length of an antenna is often stated in waves. In optics, the surfaces of lenses and mirrors are sometimes required to be polished to within a very small fraction of a wavelength of green light (546 nanometers)
