Doppler Example  fO A siren with a frequency of 2000 Hz is emitted from an ambulance which travels at a speed of 6o km/h. Calculate the observed frequency in front and behind the ambulance. Speed of sound is 330 m.s-1. = v + vO v - vS + SAMPLE ONLY fS SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> www.warnescience.net
