OK, but you're just wrong about that. observer 1 will see it reflected back to the flashlight position because a vertical flashlight will always shoot light straight up in the flashlight's own rest frame. Observer 2 will see the light come back to (position on tracks that flashlight was when it was first turned on ) + v*t.no in both cases they dont....
as u have quoted it will return to its old position(which it started propagation) which is equal to the new position of the flash light- v*t
ok here are the 3 events:
1- light emitted moving up.
2- light reflected from mirror
3- light is moving diagnolly down to the florr of the train(not back to the flash light)
in the first phase: flash light moved v*0.5t
int the third phase flash light moved v*0.5t
so what happned according to observer 1 (in the car) he sees light moving up and reflected back no to the flash light postion but flash light postion- v*t
If you disagree, can you explain why you think this is wrong? Give some type of argument as to why you don't think this is a perfectly coherent possibility? Or is it just a matter of gut feeling?
