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 ...

Reverberant sounds made in an empty environment are the result of sound waves bouncing off hard, flat surfaces, as governed by basic principles of the.

WELL, BACK HERE, MIDDLE SCHOOL STUDENTS ARE LEARNING TO BEND LIGHT AND SOUND WAVES. IT’S NOT JUST FOR SUPERHEROES. EIGHTH GRADERS AT BEEDLE MIDDLE SCHOOL EXPLORED THE LUMINARIUM TODAY. THEY DISCOVERED ...

A team of scientists has succeeded in cooling traveling sound waves in wave-guides considerably further than has previously been possible using laser light. This achievement represents a significant ...

In new research that will have implications for the development of computers, scientists have successfully stored light-based information in the form of sound waves. These sound recordings have been ...

It’s a question I’m sure was keeping you up at night: can you make an object spin with a sound wave? The answer, generally speaking, used to be no. Now, though, mechanical engineers have taken a look ...

Bengaluru: Indian Institute of Science (IISc) researchers have developed a non-invasive technique to measure blood glucose levels using polarised light and sound waves, offering hope for people with ...

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

As a physical quantity pressure is encountered in various fields: atmospheric pressure in meteorology, blood pressure in medicine, or even in everyday life with pressure cookers and vacuum-sealed ...
