Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the bright hydrogen emission lines. Key fact Line emission spectra are ...

For Absorption Spectrometer: 5mm white-light LED (light emitting diode ... In this example I’ve loaded in two images, a photo of a CFL spectrum and a photo of the emission spectrum of quinine sulfate.

This causes an absorption spectra, as shown below. Because the energy levels are the same, the lines in the emission spectra of an element are in the same position as the lines in the absorption ...
