Question
The movement of water within a wave travels ____.
in a circular path at a depth of one-half the wavelength
in an up and down motion to a depth of one-half the wavelength
with the wave
in both a longitudinal and circular path
in a circular path at and just below the water surface
a.in a circular path at a depth of one-half the wavelength
b.in an up and down motion to a depth of one-half the wavelength
c.with the wave
d.in both a longitudinal and circular path
e.in a circular path at and just below the water surface
Explanation / Answer
d.in both a longitudinal and circular path
Water waves are an example of waves that involve a combination of both longitudinal and transverse motions. As a wave travels through the waver, the particles travel in clockwise circles. The radius of the circles decreases as the depth into the water increases. The movie below shows a water wave travelling from left to right in a region where the depth of the water is greater than the wavelength of the waves. I have identified two particles in yellow to show that each particle indeed travels in a clockwise circle as the wave passes.
