1.
The space-time interval is defined as
(cΔt)2 + Δx2
(cΔt)2 − Δx2
Δx − cΔt
Δx2 − (cΔt)2
2.
For a pair of events linked by a light pulse, (Δs)2 is
infinite
positive
negative
zero
3.
Events with Δt = 1.0 year and Δx = 2.0 light-years are
space-like
simultaneous in all frames
time-like
light-like
4.
If the interval between two events is 5.0 m in S, in a frame S′ it is
greater than 5.0 m
less than 5.0 m
5.0 m
zero
5.
Which statement about time-like separated events is correct?
One can influence the other
They are always simultaneous in some frame
They lie outside the light cone
Their time order depends on the observer
6.
With c = 1, Δt = 5 years and Δx = 3 light-years give Δs of
2 years
8 years
√34 years
4 years
