Q24. Anitta and her younger sister were waiting for the transport near the School man gate. They could hear the high pitch of the siren of the approachingambulance and noticed that its pitch drops suddenly as the ambulance passes them. The younger sister who is studying in class three asked Anitta whether the driver of the ambulance and reduced the volume of the siren. Anitta cleared her doubt explaining a particular phenomenon in sound.
c) A train blows a whistle of frequency 400 Hz and moves towards a stationary listener with a velocity 20 m/s. Calculate the frequency of the whistle for the listener. The velocity of sound in air is 340 m/s
