- Gamma rays are high-energy photons produced by some of the most violent events in the universe. Photons of light are massless particles that are essentially packets of energy. Because of a quantum-mechanical phenomenon known as wave-particle duality, particles can behave like waves, and photons are no different.

May 14, 2024 · Gamma rays result from nuclear processes (usually nuclear decay), while X-rays result from interactions outside the atomic nucleus (typically from electrons). Overall, gamma rays have higher energies and shorter wavelengths than x-rays and are more penetrating.
The entire range of light, from radio waves to gamma rays, is known as the electromagnetic spectrum. The imaginary scene shown here highlights some of the natural and human-made sources of electromagnetic radiation on Earth and in space.
Nov 3, 2024 · A gamma ray is electromagnetic radiation of the shortest wavelength and highest energy. Gamma-ray radiation has wavelengths generally smaller than a few tenths of an angstrom (10 meter), and gamma-ray photons have energies greater than tens of thousands of electron volts.
- Gamma rays are produced during the disintegration of radioactive atomic nuclei and the decay of certain subatomic particles. Gamma rays are also pr...
- The term gamma ray was coined by British physicist Ernest Rutherford in 1903, following early studies of the emissions of radioactive nuclei.
- Medical applications of gamma rays include the imaging technique of positron emission tomography (PET) and radiation therapies to treat cancerous t...
It consists of the shortest wavelength electromagnetic waves, typically shorter than those of X-rays. With frequencies above 30 exahertz (3 × 1019 Hz) and wavelengths less than 10 picometers (1 × 10−11 m), gamma ray photons have the highest photon energy of any form of electromagnetic radiation.
