A meter stick, pointing in the x-direction moves along the x-axis with speed v=0.8c, with its midpoint passing through the origin at time t=0. A stationary observer situated at the origin takes a photograph of the stick at time t=0. At what poisition does the photograph show the front and back end of the stick to be at t=0?
The Attempt at a Solution
I'm confused here by the use of photograph. I've tried to use the Lorentz contraction but do I need to do it twice, once for the light going out and once for it coming back to the photographic plate? Very confused and all help/guidance gratefully accepted.
