Emission theory
Emission E*mis"sion, n. [L. emissio: cf. F. ['e]mission. See {Emit}.] 1. The act of sending or throwing out; the act of sending forth or putting into circulation; issue; as, the emission of light from the sun; the emission of heat from a fire; the emission of bank notes. [1913 Webster]

2. That which is sent out, issued, or put in circulation at one time; issue; as, the emission was mostly blood. [1913 Webster]

{Emission theory} (Physics), the theory of Newton, regarding light as consisting of emitted particles or corpuscles. See {Corpuscular theory}, under {Corpuscular}. [1913 Webster]
