Theory Quote by Walter Isaacson
““According to the assumption to be considered here, when a light ray is propagated from a point, the energy is not continuously distributed over an increasing space but consists of a finite number of energy quanta which are localized at points in space and which can be produced and absorbed only as complete units.””
About This Quote
Source Book: Einstein: His Life and Universe, 2007
Light travels as discrete packets called quanta, not as a continuous wave, and these packets are created or destroyed whole.
In simple terms: Light is made of indivisible packets.
