What is a gamma-ray in physics?
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 (10−10 meters), and gamma-ray photons have energies greater than tens of thousands of electron volts.
Is a gamma-ray positive or negative?
As previously indicated, large unstable atoms become more stable by emitting radiation to get rid of excess atomic energy (radioactivity). This radiation can be emitted in the form of positively charged alpha particles, negatively charged beta particles, gamma rays, or x-rays.
