 Starting with the equivalence principle, Einstein deduced the phenomena of gravitational time dilation, the gravitational bending of light (albeit with the wrong value ) , and the velocity of will have increased by from its velocity when the light was emitted. The energy arriving at will therefore not be the energy but the greater energy given by
