Homework Statement
Consider two events
[tex]ct_{1}\; =\; 3\; m,\; x_{1}\; =\; 2\; m,\; ct_{2}\; =\; 5\; m,\; x_{2}\; =\; 6m[/tex]
- What is the time difference between the two events?
- Find a reference frame for which the time difference is the negative of the time difference in the original frame.
- Calculate the invariant interval [tex]\left( \Delta s \right)^{2}=+c^{2}\left( t_{2}-t_{1} \right)^{2}-\left( x_{2}-x_{1} \right)^{2}-\left( y_{2}-y_{1} \right)^{2}-\left( z_{2}-z_{1} \right)^{2}[/tex] in both frames.
Homework Equations
The Attempt at a Solution
I honestly don't have any idea what the first question is actually asking. How can I calculate a time difference when I am only given these distance figures with no velocities? It seems like an extremely poorly worded question.
