Two different waves with the same frequency and wavelengths can be coupled, so that the amplitude alternates periodically between the two to form a phenomenon known as a coherent beating oscillation.
In an innovative study, researchers from HSE University, RAN Institute of Linguistics, and the the Pirogov Center measured and analyzed high-frequency oscillations (HFO) in different regions of the ...
