- (Technically, all photons emitted by atomic nuclei are classified as gamma rays, even the rare ones of less than 100 keV.) As extreme as these processes may be, we bask in their glow every day: sunlight started off as gamma radiation in the sun’s core and degraded into visible light during its tortuous passage through the overlying layers of gas.

A gamma ray, also known as gamma radiation (symbol γ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves, typically shorter than those of X-rays.
May 14, 2024 · Gamma rays are light , not particles. They have the highest frequency and shortest wavelength on the electromagnetic spectrum. Mostly, gamma radiation results from nuclear reactions.
Nov 3, 2024 · Gamma ray, electromagnetic radiation of the shortest wavelength and highest energy. Gamma rays are produced in the disintegration of radioactive atomic nuclei and in the decay of certain subatomic particles. It includes some overlap with X-rays in the electromagnetic spectrum.
- A gamma ray is electromagnetic radiation of the shortest wavelength and highest energy. Gamma-ray radiation has wavelengths generally smaller than...
- 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...
Gamma rays, X-rays, and extreme ultraviolet rays are called ionizing radiation because their high photon energy is able to ionize atoms, causing chemical reactions. Longer-wavelength radiation such as visible light is nonionizing; the photons do not have sufficient energy to ionize atoms.
Dec 28, 2022 · On Earth, gamma rays are produced by radioactive decay, nuclear weapons and lightning, while in space they are produced by violent, high-energy sources such as solar flares, quasars, black holes...
Nov 14, 2014 · Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons , each traveling in a wave-like pattern at the speed of light .
