Homework Statement
It is not a homework question.I am trying to understand the concept in the attached diagram but I stuck.Hope someone can help
Homework Equations
The Attempt at a Solution
Please see the lower part of the note,stating that Δt' = Δt/γ.However,imagine you are in the moving frame S'(the stationary train).Yes just a stationary train.If you shine a beam towards the head and back of the train,they should arrive at the same time(in your frame).Hence Δt' = 0,but this also implies Δt = 0.What's wrong?
Thanks!
