Radiation

In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium. This includes: electromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ) particle radiation, such as alpha radiation (α), beta radiation (β), proton radiation and neutron radiation (particles of non-zero rest energy) acoustic radiation, such as ultrasound, sound, and seismic waves (dependent on a physical transmission medium) gravitational radiation, radiation that takes the form of gravitational waves, or ripples in the curvature of spacetimeRadiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles.

Ray

A narrow stream of radiant energy, especially visible light, traveling in a straight or nearly straight line.

Radiation

The act or process of radiating
The radiation of heat and light from a fire.

Ray

A narrow stream of particles such as protons traveling in a straight or nearly straight line.

Radiation
