What Does the Spectrum of a Star Tell Us about Its Temperature?
ES2803  Peak Emissions for Spectral Groups

Stars in the same spectral group usually have a fairly narrow range of peak emission wavelengths and temperatures. These graphical spectra show the peak emission wavelength for each of the 12 spectra you sorted.

6. Record the peak emission wavelength for each star's spectrum.

7. Based on the peak emission wavelengths and the temperatures of the standard stars, estimate the temperatures of stars in each category.
(Refer back to step 6 if necessary.)
