If we run two identical lasers and put one at sea level and one on top of a high mountain, will they operate at different frequencies?
All of the above still applies. It will be slower than normal for any clock above it, faster for any clock below it, and unaltered for a clock right next to it.Shouldn't the clock (laser) on the mountain be slower?
The second and third are the same.First is a red shift given by the recession velocity (or general expansion of the Universe) second by the red shift caused by light having to make its way out of the gravitational field and third by the light having come from a star, quasar or other with a strong gravitational field where time and chemical processes run slower (redder) due to time being slower in the heavy gravitational field.
Excuse me if I shift to cosmology. From what I understand the observed red shift of stars should come from three factors - according to the present model - First is a red shift given by the recession velocity (or general expansion of the Universe) second by the red shift caused by light having to make its way out of the gravitational field and third by the light having come from a star, quasar or other with a strong gravitational field where time and chemical processes run slower (redder) due to time being slower in the heavy gravitational field.
