Dual nature of Light

Dual nature of Light; Add caption What are the two nature of light ?  What is meant by dual nature of light? What did Louis de Broglie discover? Is light is a wave or it is a particle or both ?Let us know all these things. . Wave nature of light;      The wave nature of light was well established by the end of the nineteenth century. The phenomena of interference, diffraction and polarisation were explained in a natural and satisfactory way by the wave picture of light. According to this picture, light is an electromagnetic wave consisting of electric and magnetic fields with continuous distribution of energy over the region of space over which the wave is extended. But the wave picture of light is unable to explain the most basic features of photoelectric emission. Photoelectric effect thus gave the evidence to the strange fact that light in interaction whit matter behaved as if it was made of quanta or packets of energy, each of energy hv. Let us now know about… Particle nature of l
