A scientific experiment is able to create a wave that is frozen in time

A scientific experiment is able to create a wave that is frozen in time "A wave is a deformation in the surface of a liquid that moves at a speed that is independent of that liquid," the researchers explain... "In our case, what occurs is actually the opposite: the water moves very rapidly (at several meters per second), but the wave moves at a speed of zero...

In order to recreate this phenomenon, the scientists constructed a small canal in a laboratory at the University. The prototype is relatively simple, they say: it consists of a semi-submerged panel with a square corner that partially obstructs the flow in a tank of water that is approximately the length of a van.
