The film explains the fundamentals of acoustics, detailing how sound waves travel through air, the effects of temperature on sound speed, and the phenomenon of refraction. It describes the anatomy of ...

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 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 ...

Artificial structures known as metamaterials can bend light, sound and other waves to generate effects not seen in nature. Now physicists in Italy have shown 1 how a metamaterial made up of tiny ...

Sound wave techniques are experimental and analytical methods that generate, manipulate, and detect acoustic waves to probe, image, or modify materials and systems. In research, they encompass ...

There are many glorious science-based terms when it comes to surfing. We all talk about swells, of course, the underwater energy that creates a breaking wave. But we'll look at swell angles and ...
