>>14382136https://en.wikipedia.org/wiki/RadiationIn 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 (?)
- particle radiation, such as alpha radiation (?), beta radiation (?), 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, that takes the form of gravitational waves, or ripples in the curvature of spacetime
