Final answer:

Redshift in light indicates motion of galaxies away or towards us based on Doppler effect.


Explanation:

Redshift refers to the change in light (to a lower frequency) emitted by neighboring galaxies due to their motion away from us. This shift in wavelength, leading to a longer wavelength and lower frequency, is a result of the Doppler effect.

For instance, if a galaxy's light waves are observed as redshifted, it indicates the galaxy is moving away from us. On the other hand, a blueshift would indicate that the galaxy is moving towards us, resulting in a shorter wavelength and higher frequency of light.
