Huygens’ Principle‚ Interference and Diffraction Huygens’ Principle In 1678‚ a Dutch physicist‚ Christian Huygens‚ studied wave behavior and proposed that the wavefronts of light waves spreading out from a point source can be regarded as the overlapped crests of tiny secondary waves – that wavefronts are made up of tinier wavefronts. Wavefronts are an array of identical waves that have the same source and travels through a homogeneous medium‚ thus their corresponding crests and troughs are in the
