Equation for redshift

WebLike the Schwarzschild radius, the gravitational redshift formula can only be gotten properly from GR. All the Newtonian analysis, in which you use the Newtonian potential, Newtonian kinetic energy etc., while giving the right answers, must be regarded as just a mnemonic to 'get' the answers. It's a matter of philosophy really.
