Overview         (For age - group : 11 - 16 )

This educational physics (atomic) animation with audio shows Bohr's creation of the atomic model in a systematic manner. It starts from the mystery of spectral lines and ends with the explanation of hydrogen spectra, an animated glossary and a quiz on Bohr's model. This animated 1.5 hour Bohr's atomic model covers in detail the endeavor of the scientists to see the unseen and is meant for high school and college atomic physics classes.

Bohr model animated relationship energy level quantum well and orbital

The animation answers the questions like What is the radius of orbits in which electrons did not radiate? What was the energy possessed by the electron in these orbits?
Bohr model animation rutherford continuous discrete atomic structure Bohr animated theory of discrete jumps of electron
The physics animation exhibits the path-breaking concepts of Bohr through comparison between orbital, energy well and energy level model and calculations for speed, energy, radius and their correlation.
Bohr energy level and discrete quantum spectra model animated with all photon values and wavelength
Animated Bohr radius, energy, speed, wavelength, spectral series - Lyman Balmer formula given
Bohr's postulates, explanation of hydrogen spectra and its line series are elaborated also the shortcomings of the model are completely covered. Our animated mascot, professor Stanley quizzes you on the concepts. An animated glossary clarifies the terms like Rydberg's constant, ionization energy, quantum well etc.
Details of the animation/ movie /software

This Bohr's atomic theory animation is directed towards high school / university students and teachers. It contains animation supported by audio and is directed towards unfolding the efforts of Bohr to apply quantum principles to Rutherford's mechanistic planetary model. Derivations, formulas, hints, explanations and glossary are provided for better grasp of the concepts. A quiz checks the understanding. Topics covered are:

  • Journey into the atom - Bohr strives to save Rutherford's model :
    Mystery of missing spectral lines from emission and absorption spectra, Rutherford's model, Bohr's postulates.
  • Visual comparison of Bohr's and Rutherford's model :
    Columbic forces balance mechanical rotation, understanding spectra, continuous and discrete spectrum, why did the electrons not fall into the nucleus? Ramp and steps and unequal steps analogy.
  • Which orbits were considered to be stationary by Bohr? : Quantifying of angular momentum
  • Derivation of L= nh/2pi : DeBroglie's equation
