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 ...
Learn about Niels Bohr's atomic model and compare it to Rutherford's model. Explore how to draw the Bohr model of hydrogen and argon, given their electron shells. Related to this Question The wavelength of first line of Balmer series in h...
To find the wave number of the first emission line of the Balmer series in the hydrogen spectrum, we can follow these steps:Step 1: Understand the Formula The wave number (ν̅) is given by the formula: \( \nu̅ = RH \left(
For example, for optical transitions with a photon wavelength of order 5000 Å (1 Å = 10−8 cm) and a dipole transition moment of order ea0 (where a0 is the Bohr radius of hydrogen, approximately 0.53 Å), the lifetime is of order 10−8 sec. The transition probability is ...
Bohr’s Atom Model 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 transi...
