Mind the Liquid Gap: Liquids Are Capable of Supporting Waves With Short Wavelengths Only
Flowing particles in liquids act as a filter to suppress long-wavelength waves but allow short-wavelength ones to be supported, according to physicists at Queen Mary University of London (QMUL). Liquids are the least understood state of matter and for a long time it has been believed that they can sustain both gas-like waves with long
