Web20. feb 2024 · What Is “Redshift?” ‘Redshift’ is a key concept for astronomers. The term can be understood literally — the wavelength of the light is stretched, so the light is seen as ‘shifted’ towards the red part of the spectrum. Something similar happens to sound waves when a source of sound moves relative to an observer.
