These ripples are waves travelling through the water. Like ocean waves, these ripples are transverse waves because the surface of the water moves up and down, at 90° to the direction that the ...
"The film first shows that the wave velocity decreases as the wave crosses a boundary from deep to shallow water. When the periodic wave is incident at an angle on the boundary of the shallow region ...
