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.
Jun 23, 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.
Aug 10, 2016 · Gamma rays have the smallest wavelengths and the most energy of any wave in the electromagnetic spectrum. They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes.
Gamma rays are high frequency (or shortest wavelength) electromagnetic radiation and carry a lot of energy. They pass through most types of material. Only something hard, like a lead block or a thick concrete block, can stop their transmission.
May 14, 2024 · Gamma rays or gamma radiation are a form of electromagnetic radiation with extremely high frequency and energy. They are a significant topic of study in fields such as nuclear physics, astrophysics, and medical science due to their unique properties and diverse applications.
Dec 28, 2022 · 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...
Jun 6, 2024 · Electromagnetic radiation - Gamma Rays, Photons, Wavelengths: Six years after the discovery of radioactivity (1896) by Henri Becquerel of France, the New Zealand-born British physicist Ernest Rutherford found that three different kinds of radiation are emitted in the decay of radioactive substances; these he called alpha, beta, and gamma rays ...
Nov 21, 2023 · The most powerful events in the known universe – gamma-ray bursts (GRBs) – are short-lived outbursts of the highest-energy light. They can erupt with a quintillion (a 10 followed by 18 zeros) times the luminosity of our Sun.
Gamma rays allow us to enrich our view of the universe beyond what we see in visible light. Along with other non-visible forms of light, gamma rays enable us to observe known objects in a new way, and they reveal phenomena never before seen.
NASA's Fermi Gamma-ray Space Telescope is a powerful space observatory that detects gamma rays, the most energetic form of light. Fermi enables scientists to address questions across a broad range of topics, from crushed stellar remnants like pulsars and the origin of high-energy charged particles called cosmic rays to stellar explosions known ...
