The Reflection of Water Waves.
What Type of Surfaces Best Reflect Water Waves?
Water
waves are best reflected from hard flat surfaces
as
shown in the picture below.
Note that the total length of the line representing the
wave
peak
stays the same where it is being
reflected.
The red part of the incident wave
plus the blue part of
the reflected
wave
is the same length as the original line.
After reflection a wave
has the same
speed, frequency and wavelength,
it is only the direction of the
wave that has changed.
