The Doppler effect is the shift in frequency of sound waves when there is motion of the source of sound, the listener, or both. Fs is the frequency of sound waves from the source.
a. Assume that the listener does not move. Find the frequency of sound waves that the listener detects (Fl) when the source of sound is moving towards the listener.
b. Assume that the listener does not move. Find the frequency of sound waves that the listener detects (Fl) when the source of sound is moving away from the listener.
c. Based on your findings in a and b, explain why you hear the higher pitch of the siren of the approaching ambulance, and notice that its pitch drops suddenly as the ambulance passes you.
d. Assume that the listener is moving towards the source of sound. Find the frequency of sound waves that the listener detects (Fl) when the source of sound is moving towards the listener.
e. Assume that the listener is moving away from the source of sound. Find the frequency of sound waves that the listener detects (Fl) when the source of sound is also moving away from the listener.
Fl is F subscript l Thanks.
