Hi,
Basically the question is about doppler shift. The formula is:
(f2 - f1)/f1 = -kT ; f1 = Freq in object rest frame, f2 = Freq in lab frame
The Q: Often, frequencies are compared to 1 part in 10^15. In order to make use of this level of accuracy, to what extent can T fluctuate?
I think I'm having a serious dumb moment. Does this mean (f2 - f1) is at least 1/10^15? i.e.) We can't discern less than that? But then what do I do; are they expecting a % error?
Thanks.
