How does the electromagnetic spectrum relate to a grouping of stars based on color?
2 answers:
From different wavelengths we can create a electromagnetic spectrum . From spectral lines of that electromagnetic spectrum astronomers can determine the element in the farther universe (star). They can also determine the temperature and density of that element in the star. The spectral lines in the electromagnetic spectrum tell us about any magnetic field of the star.
A useful formula of wavelength:
wavelength is the length 7 of wave having SI unit lambda
