Broglie’s Hypothesis: Dual nature of radiations

Louis de Broglie’s Hypothesis: (Dual nature of radiations) There arose a conflict about the nature of radiations. There were two schools of thoughts:  (i)  wave nature (ii) particle nature of radiations Both have evidences. So it is difficult to reject any. Louis de Broglie (in 1924) solved this problem by giving the idea of dual nature …

Calculate the Wave length and Wave Number of Radiations emitted

Wave length (λ) of Radiations emitted during Electron jump: When an electron jumps from one orbit to another, energy is emitted or absorbed in the form of wavelength radiations (λ). Wave Number of Radiations emitted during Electron jump: When electron jumps from one orbit to another, energy is emitted or absorbed in the form of …

Bohr Model of Atom – Class 11 Chemistry Chapter 2 Notes

Bohr Model of atom:             Neil Bohr in 1913 put forward a theory to develop atomic model and to overcome shortcomings of Rutherford model. Bohr theory has following postulates. Electrons revolve around the nucleus in fixed orbits (i.e. orbits of particular radii). Each orbit or shell is associated with a definite amount of energy. Electrons …
