gamma rays

what are gamma rays?

gamma rays are just one of the many types of electromagnetic radiation in a group of radio waves, infrared, ultraviolet, x-rays, and microwaves. gamma rays move at the speed of light and cannot be reflected light. Gamma-rays are the most energetic form of light and are produced by the hottest regions of the universe. They are also produced by such violent events as supernova explosions or the destruction of atoms, and by less dramatic events, such as the decay of radioactive material in space. Things like supernova explosions, neutron stars and pulsars, and black holes are all sources of celestial gamma-rays.

how long are gamma rays?

gamma rays are the highest energy EM radiation and typically have energies greater than 100 keV, frequencies greater than 10


19


Hz, and wavelengths less than 10 picometers.

Gamma rays travel at the speed of light and exist only as long as they have energy. Once their energy is spent, whether in air or in solid materials, they cease to exist. The same is true for x-rays
