You are looking at 2 heated metal pieces. One looks red and the other looks green. Which one is hotter? Explain.

1. The temperature of stars in the universe varies with the type of star and the age of the star among other things. By looking at the shape of the spectrum of light emitted by a star, we can tell something about its average surface temperature. a. If we observe a star's spectrum and find that the peak power density occurs at the border between red and infrared light, what is the approximate surface temperature of the star? (Remember to include units)Incorrectb. If we observe a star’s spectrum and find that the peak power density occurs at the border between blue and ultraviolet light, what is the surface temperature of the star? (Remember to include units)Incorrect Submit QuestionQuestion 1

a. Does a hot, thin gas emit a continuous spectrum, a bright line spectra with gaps between the lines, or a dark line spectra with all frequencies except the missing (absorbed) one? b. Why do we see dark line spectra when we look at stars? c. Both hydrogen and helium glow and absorb red. Are they the same frequency of red? d. A hot solid iron plate and a hot solid aluminum plate are the same temperature. Do the give off the same range of frequencies?
