context_page_description: A spectrograph is an instrument that breaks up a wave into a frequency spectrum. These could be sound, light or radio waves. For example the frequency spectrum of light is the brightness and the amount of each colour. There are several kinds of machines called spectrographs, used to look at different waves. The term was first used in 1884.
  A spectrograph is closely related to a polychromator.
