Photon gamma def
WebA gamma particle is known by other names, such as X-ray, photons and light. Low-energy forms are called ultraviolet rays, infrared rays, even radio waves! A photon is one of the fundamental particles in nature and it plays an important role in being involved in the interactions between electrons. Photons are the most familiar particles in ... WebGamma decay is one type of radioactive decay that a nucleus can undergo. What separates this type of decay process from alpha or beta decay is that no particles are ejected from the nucleus when it undergoes this type of decay. Instead, a high energy form of electromagnetic radiation - a gamma ray photon - is released. Gamma rays are simply …

A gamma ray, also known as gamma radiation (symbol γ or ), 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 (3×10 Hz), it imparts the highest photon energy.
