Hello everyone
I've starting to learn about Hubble's law and I have a very simple question. How are the velocities to distant objects calculated from a redshift? I understand the basic principle, that faster objects have longer wavelengths, but I'm not sure about the formula which links the two.
The wikipedia page has some formula for redshift, but the cosmological formula doesn't seem to have a term in velocity.
Many thanks in advance
Chris
