Einstein defined a pocket of energy with zero rest mass (photon)
and explained the both double-slit experiment and the
photoelectric effect. On the other hand it seems, Einstein himself
did not accept wave-particle duality and knew that as only a
temporary way out. But because of the prestige of Einstein, only a
few scientists have investigated the possibility of a non-zero rest
mass of the photon with few results.
In this article, we present a new proof of wave-particle duality of
the light. Consider a particle that is separated from a moving
source. The motion of the particle is always affected by the
movement of its source. Now notice how the electrons move in an
atom. In this situation, the electron has two kinds of motion,
moving around itself and around the nucleus of the atom. Like the
Earth that rotates around itself and simultaneously orbits around
the sun.
When the electron is excited, it emits a Photon the motion of the
photon is affected by the motion of its source, Electron, and must
include both types of motion of its source. So, the photon is a
particle that always traverses on helical direction and has a threedimensional motion.
In Saleh Theory, since the photon has a projectile and impulsive
motion, it is a particle. On the other hand, as it has a rotational
motion, it behaves wavelike. In other words, on the true nature of
the photon, we can say:
“The photon is a particle that traverses like a wave.”
