A flash of light is emitted at point O and is later reabsorbed at point P. In frame S, the line OP has a length l and makes an angle theta with the x axis. In a frame S' moving relative to S with a constant velocity v along the x axis:
How much time tau' elapses between emission and absorption of the light?
The answer is (1-betacos(theta))gamma*l/c, where beta=v/c
How does one get this answer?
