When photon was emitted, it had given frequency which is defined relative to time. As Earth moves at relativistic speeds relative to the original source of the photon, time we experience doesn't match the original source. When we measure the frequency of that photon using our time, the frequency appears to be red-shifted. If we were able to somehow measure the frequency of the photon relative to the time of the source, it would still have exactly the correct frequency. | |
