Which radiation particle is pure energy waves?

Gamma radiation is electromagnetic energy carried by photons. Photons have no rest mass and no electric charge, so gamma rays are energy quanta that behave like waves of light at very high frequencies. They come from nuclear transitions and can penetrate materials more deeply than charged particles. The other options are actual particles with mass: an alpha particle is a helium nucleus, beta radiation involves fast electrons or positrons, and a neutron is a massive neutral particle. These are not pure energy waves, so gamma radiation best fits the description.
