Astrophysics
Sometimes called radiation or light. The entire range of wavelengths of electromagnetic radiation includes radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays, and gamma rays. It is created by a time varying electric field intertwined with a time varying magnetic field. The first field propagates the second, which again propagates the first, and so on.
