But some new phenomenon observed during the last decade of 19 th century which are not explained by classical physics. Thus to explain their phenomena a new revolutionary concept was born which is known as Quantum physics developed by many outstanding physicists such as Planck, Einstein, Bohr, De Broglie, Heisenberg, Schrodinger, Born, Dirac and others. The quantum idea was 1 st introduced by Max Planck in 1900 to explain the observed energy distribution in the spectrum of black body radiation which is later used successfully by Einstein to explain Photoelectric Effect. Neils Bohr used a similar quantum concept to formulate a model for H-atom and explain the observed spectra successfully. The concept of dual nature of radiation was extended to Louis De Broglie who suggested that particles should have wave nature under certain circumstances. Thus the wave particle duality is regarded as basic ingredient of nature.
