If the spectrum of a star is red shifted, it is moving away from you. True False

Answer

True.

Explanation

When the spectrum of a star is red-shifted, it indicates that the wavelengths of light emitted by the star are being stretched. This phenomenon occurs when the star is moving away from the observer. In astrophysics, redshift is associated with the Doppler effect, where the observed frequency of light decreases (or shifts towards the red end of the spectrum) as the source of the light recedes from the observer. This can also be a key observational evidence for the expansion of the universe, as many distant galaxies are observed to be red-shifted, suggesting they are moving away from us. Thus, a redshift in a star's spectrum is indeed indicative of its motion away from the observer.
