Water Waves - Diffraction.
The wavelength of water waves may be
several metres.
If the wavelength is of a similar size to a gap
in a harbour wall,
then the wave will diffract as shown
below.
If the wavelength does not match the
size of the gap,
then only a little diffraction will occur at the edge of the wave.
The part of the wave
which hits the wall in the above two
pictures
is reflected
straight back on itself.
