The Sun's spectrum contains spectral lines from neutral sodium and calcium as well as ionized magnesium and iron. Of the choices below, which could be the surface temperature of the Sun?
A. 4,200 K
B. 5,800 K
C. 8,900 K
D. 14,300 K
The correct answer of the given question above would be the second option, option B. 5,800 K. The surface temperature of the Sun is 5,800 K since given above, the Sun's spectrum contains spectral lines from neutral sodium and calcium as well as ionized magnesium and iron. Hope this answer helps.
