Question

The proper time between two events is measured by clocks at rest in a reference frame in which the two events: The proper time between two events is measured by clocks at rest in a reference frame in which the two events:
a. are separated by the distance a light signal can travel during the time interval
b. occur at the same time
c. satisfy none of the above
d. occur in Nashville occur at the same coordinates

Answer 1

Answer:

a - As long as the time between 2 events is reconcilable with a light signal, the time between the events, in that frame, can be determined.

Answer 2

The proper time between true events as measured by car
