Redshifts were used as supporting evidence for the big bang theory.

Which describes redshifts? Check all that apply.

The light source and observer move closer together.
Observed light shifts to a longer wavelength.
They indicate receding galaxies.
Observed light shifts to a shorter wavelength.
The light source and observer move farther apart.
They indicate approaching galaxies.

Respuesta :

The statements observed light shifts to a longer wavelength, indicating receding galaxies and the light source and observer moving farther apart are all issues that describe redshifts.

What are redshifts?

Redshift is a term used in the physics discipline to describe a given increase in the emitted wavelength associated with less photon energy, which was described by observing galaxies that shifted to more extended wavelengths.

In conclusion, the statements observed light shifts to a longer wavelength, indicating receding galaxies and the light source and observer moving farther apart are all issues that describe redshifts.
