radiation radiation
radiation , term applied to the emission and transmission of energy through space or through a material medium and also to the radiated energy itself. In its widest sense the term includes electromagnetic, acoustic, and particle radiation, and all forms of ionizing radiation. Commonly radiation ... Read more
synchrotron radiation synchrotron radiation
synchrotron radiation in physics, electromagnetic radiation emitted by high-speed electrons spiraling along the lines of force of a magnetic field (see magnetism ). Depending on the electron's energy and the strength of the magnetic field, the maximum intensity will occur as radio waves, visible... Read more

infrared radiation infrared radiation
infrared radiation electromagnetic radiation having a wavelength in the range from c.75 × 10 -6 cm to c.100,000 × 10 -6 cm (0.000075-0.1 cm). Infrared rays thus occupy that part of the electromagnetic spectrum with a frequency less than that of visible light and greater than... Read more
