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. The CFL lines are shown below. A built-in intensity-measuring tool is used ...

This causes line emission spectra to be produced, as shown below. This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of ...

The wavelength spectrum of the measured light ... allowing for better measurement of low wavenumber Raman emission (e.g., < 100 cm-1). The first example [Fig. 1] shows the suppression of long ...

Colors of emission spectra are due to loosely-bound valence electrons being excited in a flame and dropping back down while emitting light. Warning! Once the flame has started, DO NOT add more ...

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 ...
