Physics Special Relativity Time Dilation Question????? 1. The problem statement, all variables and given/known data Which of the following situations is the time interval between the two events in one frame equal to y(gamma) multiplied by the time interval in the other frame? 1. 2 Rocketships pass each other in space with high a high speed. In the first rocket ship, the captain opens a fridge door(event #1) and than closes the fridge door (event #2) 5 seconds later according to the watch of the captain The 2 rocketships are the two frames. 2. A high energy electron is emitted (event #1) by a far away star, and the star is moving fast away from the Earth. The electron is however moving toward Earth and is detected (event #2) upon arrival there. The Earth and the Star are the frames. 2. Relevant equations Delta T (original) = delta T/y(gamma) where the time interval in which the event occurs at rest is Delta T (original) and Delta T is the time interval in which the observer sees it. 3. The attempt at a solution So, i have to try to find when delta T in one frame equals delta t (original) x y(gamma) in the other frame. SO in general, the sequence where it includes time the event occurs at rest is when delta t = delta t (original) x y(gamma) right? Please help out, Thanks!
