WebA collimated beam of light or other electromagnetic radiation has parallel rays, and therefore will spread minimally as it propagates.A perfectly collimated light beam, with no divergence, would not disperse with distance.However, diffraction prevents the creation of any such beam. Light can be approximately collimated by a number of processes, for instance by … WebRadiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells.
