An ambulance siren sounds at a frequency of 700.00 Hz. The ambulance is travelling toward a bus at speed 100.00 km/h. The bus is driving away from the ambulance with a speed of 30.00 km/h. The speed of sound in air is 1230.00 km/h. For the ambulance driver, there is a beat pattern between the sound of the siren reaching him directly and the siren sound reflected from the bus. What is the frequency of these beats?
