Transitions between different electronic energy levels in elements occur at unique energies and intensities, giving each element a distinctive emission spectrum. When the energy of an incident photon ...

A set of five gas discharge tubes are arranged such that when they are touched with a Tesla coil, their characteristically colored emission spectra are seen. The Tesla coil can burn your skin on ...

Salt slurries in petri dishes with methanol are ignited and characteristic colors for various metals are observed. Colors of emission spectra are due to loosely-bound valence electrons being excited ...

Optical emission spectrometers determine analyte concentration via a quantitative measurement of the optical emission from excited atoms. When a material is heated sufficiently it will emit visible ...
