A parked ambulance is 100 m away from a girl and 900 m away from a boy :
A) the girl will hear a higher pitch than the boy
B) the boy will hear a higher pitch than the girl
C) both hear the same pitch
D) none
I think I remember this from high school
The Doppler effect says that the pitch of the sound will be lower as the distance from the object increases
So (A) is correct
+9
