The Doppler effect
is defined as the apparent change in frequency of a wave, caused by the
relative motion between the wave’s source and the oserver. The Doppler effect
can be observed with any wave producing source.
A common example of
Doppler shift is the change of pitch heard

higher during the approach, identical at the instant of passing by, and lower
during the recession.
