Hi!
I am dealing with the propagation of electromagnetic emissions through the atmosphere. To quickly outline:
Imagine some charge distribution flying at relativistic speeds and inducing a four-potential A. We define some retarded time at which the charges are at some positions, and calculate...
I noticed, I copied the Latex code and forgot to swap out the beta... the upper beta should be a nu.
I think I see what you mean, can you tell me how to justify it properly? Something like symmetry between nu and mu because it's both times contracted with the momentum?
Thank you a lot!
Hello everyone!
It seems I can't solve this exercise and I don't know where I fail.
By inserting the metric on the lefthand side of I. and employing the chain rule, the equation eventually reads (confirmed by my notes from the tutorial):
$$m\frac{\mathrm{d}p_\delta}{\mathrm{d}t} =...
