The frequency will sound different if we hear a sound source moving relative to us. This phenomenon is called the Doppler Effect in Physics. An ambulance sounds a siren at 1515 Hz and passes a cyclist moving at 2.12 m / s. After the ambulance passed, the cyclist heard a siren sound at a frequency of 1501 Hz. The speed of sound in the air is about 343 m / s. What is the speed (speed) of the ambulance in...
