![]() Planck’s hypothesis that energy is radiated and absorbed in discrete “quanta” (or energy packets) precisely matched the observed patterns of blackbody radiation and resolved the ultraviolet catastrophe.īased on this hypothesis, Bohr postulated that an atom emits or absorbs energy only in discrete quanta corresponding to the absorption or radiation of a photon. Planck’s law is a pioneering result of modern physics and quantum theory. Planck’s quantum hypothesis ( Planck’s law) is named after a German theoretical physicist Max Planck, who proposed it in 1900. The Bohr model adopted Planck’s quantum hypothesis, and he proposed a model in which the electrons of an atom were assumed to orbit the nucleus but could only do so in a finite set of orbits. the light they emit should have a continuous spectrum.The classical electromagnetic theory makes three entirely wrong predictions about atoms: ![]() This model provides especially the solution to the problem of the failure of classical physics in the field of atomic physics. In atomic physics, the Bohr model of the atom (also known as the Rutherford-Bohr model) is the modern model of the hydrogen atom introduced by Danish physicist Niels Bohr working with Ernest Rutherford at the University of Manchester in 1913. All features of Bohr’s model of the atom can be summarized in Bohr’s Postulates. In atomic physics, the Bohr model of the atom (also known as the Rutherford-Bohr model) is the modern model of the hydrogen atom introduced by Danish physicist Niels Bohr.
