Science Buddies: "Ask an Expert"

According to Newton's Corpuscular Theory "The corpuscles(Similar to Photon) are emitted from the luminous sources such as Sun, candle, electric lamp etc." , however according to modern science every electron emits light when present in exited state . So Can Every Entity be considered as a luminous source or if not then is the definition of source of corpuscles limited in the Newton' Corpuscular Theory.

Hello,

Non-visible light has not been discovered at Newton's time. So in some sense yes, his definition of light source is limited to visible light only.
