Calculate the Wave length and Wave Number of Radiations emitted

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