In the new device, an array of 256 speakers, each about 1 centimeter wide, faces another, identical speaker array across a distance of 23 centimeters. The speakers emit sound waves at frequencies too ...

Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely ...

Save your breath: A new way to make bubbles requires only sound waves. Scientists made the bubbles in levitated drops of liquid, held aloft with sound waves. Tweaking the sound waves caused the ...

THE experimental results reported in a previous communication 1 confirm the existence of several maxima for the second- and the third-order diffraction lines at oblique incidence and at low sound ...

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 ...

A research team has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does. The findings shattered ...
