Question

a listener approaches a stationery source of 500Hz twice the speed of the sound. what frequency does the listener hear​

Answer 1

Formula of the Doppler effect

f'= ((v + vo) /(v - vs)) f

f' = observed frequency

f = actual frequency

v = velocity of the sound waves

vo = velocity of the observer

vs= velocity of the source

Put the values in the equation and find the answer.
