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.
5 de oct. de 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.
10 de ago. de 2016 · Gamma-ray bursts are the most energetic and luminous electromagnetic events since the Big Bang and can release more energy in 10 seconds than our Sun will emit in its entire 10-billion-year expected lifetime! Gamma-ray astronomy presents unique opportunities to explore these exotic objects.
14 de may. de 2024 · Gamma rays are high-energy electromagnetic waves that result from nuclear processes or cosmic events. Learn about their discovery, interaction with matter, shielding, and uses in medicine, industry, and science.
28 de dic. de 2022 · Gamma rays are the most energetic form of light, produced by violent events in the universe and on Earth. Learn how they were discovered, how to stop them, how they are used in medicine and how to observe them from space.
24 de dic. de 2015 · Gamma rays are the strongest form of radiation, composed of pure energy and not subatomic particles. They are produced by nuclear reactions in celestial bodies and cosmic rays, and have varying energy levels depending on the source.
Gamma rays are the most energetic form of light, with wavelengths smaller than the nucleus of an atom. Learn how they are produced, detected, and studied by NASA's Compton Observatory and other instruments.
