SUMMARY

The discussion focuses on the synchronization of clocks in the context of special relativity, specifically using Lorentz transformations. A person "A" at a train station observes a train moving at 3/5c, while person "B" on the train synchronizes his watch with "A" and sends a light signal to person "C" at the back of the train. The key question is determining the time displayed on watches "A" and "C" when "C" passes "A". The solution involves calculating the time intervals between events as perceived by different observers, utilizing the principles of time dilation and Lorentz transformations.

PREREQUISITES
  • Understanding of Lorentz transformations
  • Knowledge of time dilation in special relativity

Homework Statement



A person "A" with a watch is standing on a train station. A train (which proper length is 100ms*c) passes him with a speed of 3/5c. A person "B" sitting on the front of the train synchronizes his watch with the "A" (both set to 0) when he passes him. At the same time he sends a light signal to another passenger "C" who is on the back of the train. Once "C" receives the signal, he synchronizes his watch (taking it -100ms back to adjust for light travel).
What "A" and "C" watches are going to show when "C" passes "A"?

What happened to part 3 of the template? Where is your attempt at a solution? You must provide this, site rules require it.

Also, this isn't advanced physics: thread moved.

You have two events here:
1. Person B passes Person A.
2. Person C passes Person A.

What is the time interval (##\Delta t##) between these two events according to the observer (person A) on the track? What is the time interval (##\Delta t^\prime##) according to the observers (persons B and C) on the train? How are these two related to each other?
