Effect
The Doppler
effect is the
change in
frequency or
pitch
of the sound
detected by
an observer
because the
sound
source and the
observer have
different
velocities with
respect
to the medium of
sound

, The Doppler Effect II—moving listener, moving source
• As the object making the sound moves or as the listener
moves (or as they both move), the velocity of sound is
shifted enough to change the pitch perceptively.
