The discussion revolves around the synchronization of two clocks in different reference frames, specifically addressing the time offset observed in one frame compared to another. Participants explore the factors involved in this offset, including the proper length of the body and the implications of special relativity.
Participants express differing views on the correct formulation of the time offset, with some asserting the presence of a factor of ##c^2## and others questioning the need for a factor of ##\gamma##. The discussion remains unresolved as multiple competing views are presented.
There are indications of confusion regarding the derivation of the time offset and the appropriate factors to consider, highlighting potential limitations in the explanations provided in the referenced textbook.
I'm pretty sure the offset in time is Lv/c2, not Lv/c (since obviously Lv/c is in units of length).Physgeek64 said:Why is it that for two clocks that are synchronised in one frame, S, but not in another, S', is there an offset in the time by a factor of ##\frac{Lv}{c}##, as measured in S'. Where L is the proper length of the body, as measured in S. I'm confused as to why there is not a factor of ##\gamma## here
Many thanks

Also section 11.3 of this link has a problem that comes up with your Lv/c involving synchronized clocks on a train. It has a nice picture too showing the distance the photon must travel, which gives those two factors.

Haha no it definitely could be clearer, but it does have a good picture I think.Physgeek64 said:How careless of me- I did mean over ##c^2##. Funnily enough, this was the book that caused my confusion. I don't feel like he explains it very well. However, I have since worked it out- so all it good.
Thank you for replying though- it's very appreciated :)
