What difference does it make if the pitch changes as the train passes? None. The concert is over by then, the train's part was played only when it approaches. My point was that phyical effects change the frequency from that emitted by the source, and this can be compensated for in advance. If the tone change as the train passes the station really bothers you, change things so that the train blows its horn as it moves away instead of approaching, so the tone heard by the audience never changes, and the pitch of the horn installed on the train must be of a higher frequency than 440 Hz.
From: BURT on 22 Mar 2010 23:14 Energy flow and gravity strength define the two rates that come togetehr as one time for matter. Synchronizing one clock in the two rates of energy flow through space and gravity strength is important. The first thing that needs to be done is to bring the clocks together in gravity and motion. Then they are synchronized. Mitch Raemsch

And if it goes to zero what about all the other angles of absorption from sides to front and back? Mitch Raemsch

Hey idiot the rate of a clock moving wrt you is at 1/gamma at all times. The GPS clock send a signal to the ground clock that the passage of a ground clock second took place after the passage of (N +4.15) periods of Cs 133 radiation on the GPS clock. Doppler shift got nothing to do with this operation. Ken Seto - Hide quoted text - > > - Show quoted text - |
