Time dilation from proper time
A clock moving at \(0.46c\) in a particle accelerator timing run measures proper time \(3\,\mu\text{s}\). Calculate the time measured in the lab frame. Enter the numerical result and choose the interpretation that matches the physics meaning.
Worked practice: physics data and result
Read the physical quantities first, then calculate the result and state what it means.
