The horn on a motor scooter emit sound waves with a frequency of 440 Hz. The driver blows the horn as the scooter moves towards you at a speed of 12.5 m/s. What is the frequency of the sound you hear? Assume the temperature is 20°C.
Knowns Unknown
v = vd = fd = ?
vs = fs =
Solve for the Unknown Use fd = fs[(v-vd)/(v-vs)] with vd = 0 m/s
Evaluate the Answer
