The word photon was coined by Gilbert Lewis. Though the concept of light in the form of discrete set of particles had been around for centuries, and had been formalized by Newton, in his theory of Light.
After successful explanation of Reflection, Refraction, Interference, Diffraction and Polarization, the wave properties of light became more obvious and scientists had thrown the particle theory of light out the of the box.
In the modern era when Planck's revolutionary idea that the energy of EM waves is quantized and the packets of energy he called as quanta, it explained the problem (Scientists around the globe struggling to explain from many years) of Black body radiation successfully.
After Albert Einstein explained the Photo-Electric Effect and realized that light energy is being quantized. Then the particle theory of Light brought to limelight. When Arthur H. Compton won the Nobel Prize for his Photon-Electron scattering studies, most scientists accepted that light quanta have an independent existence, and the term photon was accepted.
photons one of the elementary particles that are described as a necessary consequence of physical laws having a certain symmetry at every point in space time.
Photons are the most abundant particles in the Universe.
The photon concept has led to tremendous advances in experimental and theoretical studies, such as lasers, Bose- Einstein Condensation and Quantum Field Theory.
The energy of a photon related to an electromagnetic wave whose frequency is ν is given by E= hν = hc/ λ , where h, c are fundamental universal constants, 6.625 x 10>-34 Js and 3 x 10>8 m/s respectively.
Rest mass of Photons is Zero, and the dynamic mass of a photon is m = E/c>2 or E=hν/c^2
Momentum of the Photon is P = mc = h/ λ = hν/c
Spin of the Photon is 1 , it obeys Bose-Einstein Statistics
