1.
Two events are simultaneous at different places in S. In S′ moving relative to S they are
impossible
always simultaneous
generally not simultaneous
at the same place
2.
In the train thought experiment, the platform observer finds the light reaches the back wall first because
the back wall moves towards the light
the lamp moves
time stops
light moves faster backwards
3.
Order of events can differ between observers only if the events are
at the same place
light-like
time-like separated
space-like separated
4.
Which is invariant between frames?
Whether two distant events are simultaneous
Whether two events coincide in space-time
Distance between the events
Time between the events
5.
In S two events with Δt = 0 are 6.0 × 108 m apart. In S′ at 0.60c (γ = 1.25) Δt′ has magnitude
1.2 s
0 s
0.90 s
1.5 s
6.
Why can relativity of simultaneity not violate causality?
Reordered events cannot be connected by signals at or below c
All events are time-like
Light can be overtaken
Time is absolute
