Homework Statement
The question is quite basic; what is the Lorentz transformation of the follows 4-vectors from S to S' frame:
A photon (P) in S frame with 4-momentum
P = (E/c,p,0,0) and
frequency f where
hf = pc = E. h is the planks constant, p is the magnitude of 3-momentum and E is energy.
S' frame travels in positive x direction with position v speed (ie. not an ANTIPARTICLE).
...so how's P' related to P? P' is momentum in S' frame
My attempt:
Lorentz boost, simple gamma factor (sqrt (1-(v/c)^2)) relationship with P to give a P' answer as
P' = √(1-(v/c)^) * P
Correct?
How above the relationship of f and f'? f' is the frequency of photon in S' frame.
My attempt:
Same as above, gamma relationship with f to give
f' = √(1-(v/c)^) * f
Correct?
Thanks everyone
