Answer:
The amplitude is
Explanation:
From the question we are told that
The frequency of when sound is approaching observer is
The frequency as the move away from observer is
The time between the pitch are
Here you are the observer and your friends are the source of the sound
The period is mathematically evaluated as
as it is the time to complete one oscillation which from on highest pitch to the next highest pitch
Now T can also be mathematically represented as
Where is the angular velocity
=>
=>
Now using Doppler Effect,
The source of the sound is approaching the observer
The
Where A is the amplitude
So when the source is moving away from the observer
Here is the fundamental frequency
Dividing the both equation we have
=>
