- Gamma rays are light (photons), not particles. They have the highest frequency and shortest wavelength on the electromagnetic spectrum. Mostly, gamma radiation results from nuclear reactions.

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.
May 14, 2024 · High Energy: Gamma rays have very high energy, often measured in keV or MeV (mega-electronvolts). Speed : Like all electromagnetic waves, gamma rays travel at the speed of light (approximately 3×10 8 meters per second in a vacuum).
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.
Aug 29, 2023 · Gamma Rays. The part of the electromagnetic spectrum with the longest wavelength and lowest frequency is radio. The portion with the shortest wavelength and highest frequency is gamma radiation. Visible light, which is the portion of the spectrum that we can see, is roughly in the middle.
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...
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 .
