Standing waves.
A seesaw to visualize how standing waves move in an enclosed basin.
In enclosed basins, standing waves can occur. In the simplest case, they have a node in the middle and the largest amplitudes at the edges of the basin. The movement of the water’s surface then closely resembles that of a seesaw.
A seesaw. Largest amplitudes at the ends, node in the middle.
Extremely simple but extremely effective visualization!
