{Yes or No, An optical instrument for measuring the absorption of light by chemical substances; typically it will plot a graph of absorption versus wavelength or frequency, and the patterns produced are used to identify the substances present, and their internal structure is called a spectrometer. + Yes - No
 * type=""}

{True or False, The space shuttle Atlantis has served as a spectrograph for micrometeoroids. - TRUE + FALSE
 * type=""}

{Yes or No, A measurement of the wavelength of electromagnetic radiation, especially any of several techniques used to analyze the structure of molecules; the measurement of spectra of things other than radiation, such as the masses of molecules and their breakdown products is called spectrometry. + Yes - No
 * type=""}
