| photon |
Exchange particle of the electromagnetic interaction. The photon possesses zero mass and is electrically neutral. Photons are used for a great variety of experiments in nearly all areas of the natural sciences. At DESY, the light generated at accelerators is put to use within the Hamburg Synchrotron Radiation Laboratory HASYLAB for experiments in physics, chemistry, materials research, molecular biology, geophysics and medicine. ...

| photon |
colloquially, a "particle of light." Although light spreads as an electromagnetic wave, it can be created or absorbed only in discrete amounts of energy, known as photons. The energy of photons increases, the shorter the wavelength--smallest for radio waves, larger for visible light, largest for x-rays and gamma rays.
