1 Unit – 4 Engineering Physics OPTICS Dr. V.P.N. Padmanaban M.Sc.‚ Ph.D.‚ Associate Professor 1. Interference Interference of light waves is a superposition phenomenon. This phenomenon was first described by Thomas Young in 1801. It provided strong evidence for the wave theory of light. In Young’s interference experiment‚ an incident monochromatic light is diffracted by a slit in the first screen‚ which then acts as a point source of light that emits semicircular wavefronts. It is
