General Information About the Spectrometer
Components
- R – Tube with glowing gas
- Sp – Aperture with slit for light entry
- Ko – Collimator
- Pr – Glass prism
Function
The light emitted by the excited gas atoms is separated into its spectral components by refraction and dispersion in the prism. The image shows a line spectrum, typical for gases. Such spectrometers can be used to identify which elements are present in an unknown substance. The spectral lines „reveal“ each element.
