Check Your Understanding The light of a galaxy that moves away from us is “redshifted.” What occurs to the light of a galaxy that moves toward us?

To determine

The light of the galaxy undergoes what when it moves towards us.



Doppler Effect is defined as the transformation or change observed in the wavelength or the frequency of a light wave or a sound wave for an observer moving relative to the wave source. The relative motion between the observer and the wave source results in a change in its wavelength or frequency. The Doppler effect affects light emitted by other bodies in space.

Redshift is the shift of electromagnetic radiation towards longer wavelengths. This occurs when the light waves are spread wide apart when the wave travels away from the object...
