  • 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:

\\ \sf\longmapsto \lambda=\dfrac{c}{v}

  • c is the speed of light
  • v is the frequency
