In optics, the corpuscular theory of light states that light is made up of small discrete particles called "corpuscles" (little particles) which travel in a straight line with a finite velocity and possess impetus. This notion was based on an alternate description of atomism of the time period.

Today's quantum mechanics, photons, and the idea of wave–particle duality bear only a minor resemblance to Newton's understanding of light. In his Hypothesis of Light of 1675, Newton posited the existence of the ether to transmit forces between particles.
Newton proposed that light consists of little masses. This means that a horizontal beam of light near the earth is undergoing projectile motion, and forms a parabola. The straight line we observe is due to the fact that the speed of the particles is so great. In one microsecond, light travels 300 m.
Rather, the Opticks is a study of the nature of light and colour and the various phenomena of diffraction, which Newton called the "inflexion" of light. Newton sets forth in full his experiments, first reported to the Royal Society of London in 1672, [2] on dispersion, or the separation of light into a spectrum of its component
14 Μαΐ 2023 · Scientists and philosophers have studied light for thousands of years. The ancient Greeks thought that light came from people’s eyes, which is incorrect, but they nevertheless correctly described light rays, reflection, and refraction. Medieval Muslims...
26 Αυγ 2024 · Although Isaac Newton is well known for his discoveries in optics (white light composition) and mathematics , it is his formulation of the three laws of motion—the basic principles of modern physics—for which he is most famous.
