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 ...

These parts can also be used to create a device capable of measuring the spectrum of emitted light from photoexcited ... A light source. For Absorption Spectrometer: 5mm white-light LED (light ...

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 ...
