Question

question 9
which of the following can be determined by examining the spectrum of a star?
(check all that apply)
chemical composition
diameter
constellation
mass
surface temperature

Explanation:

Each element has a unique spectral fingerprint. By analyzing a star's spectrum, we can identify the elements present, thus determining its chemical composition. The spectrum also reveals the star's surface temperature based on the peak - wavelength of the emitted radiation (Wien's law). The diameter and mass are not directly determined from the spectrum alone, and the constellation is a matter of the star's position in the sky, not related to its spectrum.

Answer:

chemical composition, surface temperature
