Let’s make the following experiment:
A train moves in the direction B-A where A is the front end and B is the back end. There are 2 slits at both ends. Let us make 2 arrangements:
1) The source of light is put near the front end A so as to make the light signals reach A & B at the same time relative to a ground observer
2) The train observer shuts the slit B slightly after the light reaches A but before the light reaches B
Checking the order of events relative to different observers!
For the train one:
Source emits light -> light reaches A -> B shuts -> light reaches B
For the ground one:
Source emits Light -> B shuts -> light reaches A and B at the same time
Is the order of events reversed?
