Atomic physics 5: Emission lines (discrete spectrum)
It had been discovered long before the quantum theory, that every element has a special colour when put into flame. It was Gustav Kirchoff and Robert Bunsen who developed modern spectroscopy from this old method, and analysed several elements, discovered new ones and suggested that composition of celestial bodies could be determined this way.
However, it wasn't really understood, why these atoms are emitting only distinctive colours, discrete spectra, when excited in a flame or an electric discharge... until the birth of quantum physics and the atomic model of Niels Bohr! Finally we understood that there are discrete energy levels in every atom and the atoms can radiate only the energy differences of these levels. And as Einstein says about photons: colour and frequency is a linear function of energy.
This experiment shows the emission lines of mercury. The light comes from a mercury vapour discharge lamp, a slit creates a beam of light. A lens and a diffraction grating creates several pictures of the slit - which are called spectral lines. To make the UV lines of mercury visible, I used a white sheet as a screen - it is fluorescent.
