What is particle theory of lighy

1.	What is particle theory of lighy
Answer» In optics, the corpuscular theory of light, arguably set forward by Descartes in 1637, states that light is made up of small discrete particles called "corpuscles" which travel in a straight line with a finite velocity and possess impetus. This was based on an alternate description of atomism of the time period. The\xa0model of light\xa0and the\xa0particle model of light, which together describe the wave-particle\xa0duality in which\xa0light\xa0is understood to possess both wave and\xa0particle\xa0functions. The wave theory and the\xa0particle\xa0theory of\xa0light\xa0were long considered to be at odds with one another.
