Galactic Red Shift

What is the definition of redshift?

Redshift is the phenomenon of the wavelength of light appearing to increase when the source moves away from the observer

What shift is it called when an object moves towards an observer and the wavelength of light decreases

If an object moves towards an observer, the wavelength decreases and this is called blueshift

What happens to the wavelength of light as it moves towards the red end of the spectrum

The wavelength increases as light moves towards the red end of the spectrum

What happens when light waves are stretched?

When light waves are stretched the wavelength increases

As the distance of galaxies increase from earth, what happens to the redshift?

As the distance of galaxies increase, the greater the redshift
