How do spectrographs help astronomers

WebMar 8, 2024 · Every star emits radiation at different wavelengths covering large portions of the entire light spectrum. That is what is depicted above. The dark lines denote the presence of matter other than helium. The reason the lines are dark is that the emitted radiation has been absorbed by elements present in the star. WebSpectrographs Spectroscopic observational techniques transform the light from an astronomical source into its components, so that we may observe the intensity of the source as a function of wavelength (or frequency, or energy, or temperature, depending on which regime of the E&M spectrum one is in and what the convention is).
