A new self-powered water sensor uses wave energy to monitor pollutants like heavy metals, microplastics, and pesticides—no ...

The unit of frequency is hertz (Hz)., wavelength close wavelength The length of a single wave, measured from one wave peak to the next. and the speed of water waves.

Researchers have discovered various topological structures in water waves (skyrmions, merons, Möbius and vortices with different topological charges), observed manipulation of floating particles ...
