Doppler Effect...Ahhhh!
A student in a parked car honks the horn, which has a `proper' frequency of 310.00 Hz. An observer in an approaching vehicle measures the frequency of the sound to be 342 Hz. Calculate the speed of the approaching vehicle. Use 340 m/s as the speed of sound in air.
Fo / V + Vo = Fs / V + Vs
Fs = 310 Hz
Vs = 0 m/s
Fo = 342 Hz
Vo = ?
V = 340 m/s
Vo = (Fs / V + Vs) * (V / Fo)
I know this is where I am messing up because I am not getting the right answer. Can someone show me where I am going wrong.
