Sections

Title

Atomic Spectra

Synopsis

Demonstrates the visible spectra of a number of gases and the analytical power of spectral analysis. Introduces Rutherford’s model of the atom and explains the significance of his scattering experiments. Shows how elements have unique line spectra and compares continuous and line absorption spectra. Demonstrates the conditions necessary to produce line emission and line absorption spectra. Shows the use of line spectra in the study of the universe and identification of substances.

Title

Hydrogen Spectrum, The

Synopsis

Demonstrates how to quantitatively analyse the hydrogen gas spectrum using the Rydberg equation. Introduces the idea of energy levels within the hydrogen atom. Uses the Doppler effect to show a connection between absorption spectra and the motion of galaxies. Shows how Maxwell’s theory of electromagnetism undermined the planetary model of the atom. Explains the quantum implications of line absorption and line emission spectra and shows how to use the Balmer equation in relation to wavelength and energy levels.
