l. Given two eventswith a fourvector interval between
them
[4,5,0,0]
Is the interval time like? ff so, find the speed of the frame in which the two events occur at the same place
and the time betweenthem.
Is the interval space
like? If so, find the speed of the frame in which the two events occur at the same time
