What would the spectrum of an auroral display look like? Why? a. It should look like the usual solar spectrum with absorption lines. Earth's upper atmosphere is heated by solar radiation. b. It should look like an emission line spectrum. The light is produced by atoms in Earth's upper atmosphere excited from collisions with particles from the solar wind. c. It should look like spectra of the Sun's chromosphere, with strong emission lines of hydrogen. The light is produced by atoms in Earth's upper atmosphere excited from collisions with particles from the solar wind. Od. It should look like a spectrum of a solar prominence, with strong influence of the magnetic field. Auroral displays are caused by the solar wind.
