AI Summary
Germany and the University of Erlangen-Nuremberg, the researchers found that negative pressure can be measured by monitoring the changes in light velocity and sound frequency within the liquid-filled optical fibers. This new method has the potential to advance our understanding of negative pressure in various scientific fields.
Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers have now discovered a new method to measure it. In collaboration with the Leibniz Institute of Photonic Technologies in
