Standing waves may be produced easily in
water, string, and air columns.
the change in frequency due to the relative
motion of the wave source and the observer
The observed frequency is higher when the
source and observer are getting closer.
The observed frequency is lower when the
source and observer are getting farther away.

The Doppler Effect
can be evident for
all types of waves –
sound, water, etc…
