Electromagnetic radiation posed a problem to the scientists for more than three centuries in that it exhibited particle and wave property at the same time. Sir Isaac Newton’s corpuscular theory reigned supreme for more than a century but later wave theory gained momentum and a heavy tussle prevailed with no conclusive verdict for either approach. At last as a compromise it was accepted that both the descriptions are acceptable but unambiguous solution of the problem of duality remained allusive. Wave property being the root for uncertainty, the principle of Heisenberg squarely blamed the microscopic inadequacy as a root cause although wave properties of the radiation may also be the cause of uncertainty. De Broglie intervened with his matter waves to account for the wave-particle duality and invokedquantum and wave mechanics to solve the dilemma. This was an imposed description whichdelayed the unambiguous solution for about a century. It was the brilliant proposal of Maxwell’s equations which on analysis unveiled the enigma of wave-particle duality of electromagnetic radiation. These radiations are not of single component but actually two components exist simultaneously which are not interconvertible. One is guided by quantum mechanics and the other by wave mechanics. While the wave character may make up for 100% of the rays, the particle part due to its quantum nature is not able to contribute to make it 100%. This bi-component model of electromagnetic radiation is able to explain the occurrence of different phenomena like Red Shift, Tunnel Effect, Photoelectric Effect, magnetic properties, electron spin etc., in an unambiguous manner without contradicting any of the accepted theories of electromagnetic radiation.
