Question
Chapter 2, Problem 2.12P
To determine
How far would the photons have fallen during their flight to the receiver if indeed they have mass if light quanta have mass, they should be attracted by the Earth's gravity, to test this hypothesis, a parallel beam of light is directed horizontally at a receiver 10 miles away?
