Emission spectra refer to the characteristic wavelengths of light emitted by sources like incandescent vapours or gases, showing specific lines on a spectrum due to the atoms, molecules, or ions present in the source. AI generated definition based on:Physics for O.N.C. Courses,1970 ...
In 1913, A Danish physicist, Neil Bohr proposed the hydrogen atom model. It explains the structure of atoms, especially the hydrogen atom. The electrons orbiting around the nucleus in the atom allowed certain stationary states with well-defined energies. When an electron transits from one state t...
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of waveleng

Niels Bohr showed that the hypothesis of optical radiation being quantized corresponded to his theory of the quantized energy levels of atoms, and thespectrumof dischargeemissionfrom hydrogen in particular. נילס בוהר הראה כי ההנחה שקרי...

When discussing Bohr’s atomic model we mentioned that atoms can undergo transitions between different states with energies E i and E k , when a photon with energy ω = Ek ? Ei (7.1) is emitted or absorbed. Experiments show, however, that the absorption or emission spectrum of an atom ...
