high frequency photons scattering following an interaction with a charged particle, usually an electron. Specifically, when the photon hits electrons...

fundamental physical constant of foundational importance in quantum mechanics: a photon's energy is equal to its frequency multiplied by the Planck constant, and...

A corona (pl.: coronas or coronae) is the outermost layer of a star's atmosphere. It is a hot but relatively dim region of plasma populated by intermittent...

high photon energy is able to ionize atoms, causing chemical reactions. Longer-wavelength radiation such as visible light is nonionizing; the photons do...

Photon is a satellite bus based on Rocket Lab's Electron kick stage. It moves satellites into their appropriate orbits once boosted by rockets such as...
