In other cases, the sample to be studied need not be contained at all. Instrumentation of UV Spectroscopy . The measured spectrum is identical to the radiation distribution expected from a blackbody, a surface that can absorb all the radiation incident on it. Similarly, light frequencies will be Doppler-shifted up or down depending on whether the light source is approaching or receding from the observer. An example of particle spectroscopy is a surface analysis technique known as electron energy loss spectroscopy (EELS) that measures the energy lost when low-energy electrons (typically 5–10 electron volts) collide with a surface. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox.

Production and analysis of a spectrum usually require the following: (1) a source of light (or other electromagnetic radiation), (2) a disperser to separate the light into its component wavelengths, and (3) a detector to sense the presence of light after dispersion. He went on to discover and measure a roughly linear relationship between the distance of these galaxies from Earth and their Doppler shift. As a result, the absorbed wavelengths will be missing from the original light spectrum after it has passed through the sample.
