3. the diagram below shows a standard spectrum compared to a spectrum produced from a distant
star
standard spectrum

spectrum from distant star
sell
visible light
which conclusion can be made by comparing the standard spectrum to the spectrum produced
from this distant star?
a. the star's spectral lines have shifted toward the ultraviolet end of the spectrum and the star
is moving toward earth.
b. the star's spectral lines have shifted toward the ultraviolet end of the spectrum and the star
is moving away from earth.
c. the star's spectral lines have shifted toward the infrared end of the spectrum and the star is
moving toward earth.
d. the star's spectral lines have shifted toward the infrared end of the spectrum and the star is
moving away from earth.
