Chronos said:Also known as a spectrograph.
turbo-1 said:And isn't the graphical readout a spectrogram? That's the common term for audio spectra.
Could be. Audio spectra are different in character, too, since they commonly have frequency on the vertical axis and time on the horizontal and vary the darkness of the plot to indicate magnitude. Some birding guides include them to characterize songs, and with a little practice, you can read them.SpaceTiger said:I've never heard that term used in astronomy, so it's probably specific to audio spectra.
A spectra graph is a visual representation of the wavelengths of light or electromagnetic radiation emitted or absorbed by a substance. It shows the intensity of the radiation at each wavelength, creating a unique pattern or spectrum.
A spectra graph is created by passing light or electromagnetic radiation through a substance and analyzing the resulting spectrum using a spectrometer. This instrument separates the different wavelengths of light and measures their intensity, producing a spectra graph as a result.
Spectra graphs can be used to analyze a wide range of substances, including stars, gases, liquids, and solids. For example, astronomers use spectra graphs to study the composition and properties of stars, while chemists use them to identify unknown substances or determine their concentration.
A spectra graph can provide information about the composition, temperature, and energy levels of a substance. It can also reveal any shifts or broadening of spectral lines, which can indicate changes in the substance's physical or chemical state.
Spectra graphs are essential tools in scientific research as they allow scientists to identify and study the properties of substances. They can also be used to detect and study changes in substances, such as chemical reactions or interactions, making them valuable in various fields such as astronomy, chemistry, and environmental science.
