Question

Which of the following can be determined by studying the spectrum of a star?

the chemicals in the atmosphere of the star
the motion of the star
the temperature of the atmosphere of the star
all of the above

Answer 1

The right answer for the question that is being asked and shown above is that: "all of the above." the following that can be determined by studying the spectrum of a star includes: the chemicals in the atmosphere of the star; the motion of the star; the temperature of the atmosphere of the star.

Answer 2

all of the above

Step-by-step explanation:

The spectrum of the star is is used to study its composition, motion and surface temperature. The absorbed or emitted wavelength indicates the elements present. The peak wavelength determines the surface temperature of the star using Wein's law. Peak wavelength is inversely proportional to temperature. The red-shift or blue shift indicates whether the star is moving away or towards us.
