The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and ...
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. The commonly accepted definitions of the gamma-ray and X-ray regions of the electromagnetic spectrum include some wavelength overlap, with ...

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). Interaction with Matter. When gamma rays encounter matter, they interact primarily through three processes:
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 quantum ...
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. With frequencies above 30 exahertz (3 × 1019 Hz) and wavelengths less than 10 ...
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. Gamma rays have a wavelength range below 100 pm and frequencies greater than 10 Hz.

Gamma rays occupy the short-wavelength end of the spectrum; they can have wavelengths smaller than the nucleus of an atom. Visible light waves are one-thousandths the width of human hair--about a million times longer than gamma rays. Radio waves, at the long-wavelength end of the spectrum, can be many meters long.
