THE interest of the subject which I propose to bring before A you this evening turns principally upon the connection or analogy between light and sound. It has been known for a very long time that ...

IT has been well established 1,2 that, in the case of diffraction of light by very-high-frequency sound waves only the first order of diffraction appears in the field of view and it attains the ...

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 ...

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 ...

When exposed to stress and strain, materials can display a wide range of different properties. By using sound waves, scientists have begun to explore fundamental stress behaviors in a crystalline ...

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 ...
