A scientist studies the light from a distant galaxy. The light from the galaxy shows a shift to longer wavelengths.

What can the scientist conclude about the galaxy?

• Claim 1; spectral lines can be obtained only from the stars that emit light towards the red end of the spectrum

• Claim 2; large galaxies only produce light that shows spectral lines towards the red end of the spectrum

• Claim 3; galaxies move apart as the universe expands, which shifts the light towards the red end of the spectrum

• Claim 4; the wavelengths of light emitted from cool surfaces are long, which shifts the light towards the red end of the spectrum.

• Increase the sizes of the cubes, and decrease the lengths of the rods.

• Decrease the sizes of the cubes, and decrease the lengths of the rods.

• Increase the lengths of the rods, and leave the sizes of the cubes the same.

• Increase the sizes of the cubes, and leave the lengths of the rods the same.

Based on the diagram, a student claims that the universe is expanding. Which statement correctly analyzes the claim?

• The claim is correct because the spectral lines shift to the red end of the spectrum when a galaxy spins faster

• The claim is incorrect because the spectral lines in the red end of the spectrum are obtained only from red giant stars in a galaxy.

• The claim is incorrect because the spectral lines in the red end of the spectrum are obtained when the light from a galaxy passes through a nebula.

• The claim is correct because the spectral lines shift to the red end of the spectrum when a galaxy moves away.
