- Redshift takes place when the source is moving away from the observer. This reduces the frequency which will in turn increase the wavelength shifting the spectrum to the red side.
- The velocity at which the source is moving away from the observer will be given by,
Here v is the recessional velocity, c is the speed of light, and z is the redshift.
