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) Web2 dec. 2024 · The Ultraviolet Catastrophe. The Rayleigh-Jeans law led to the “ultraviolet catastrophe” because it predicted that black bodies at thermal equilibrium would keep getting brighter and brighter at higher frequencies of radiation, and that the total power radiated per unit area (corresponding to ultraviolet light) of the black body would be ...
