Add Yahoo as a preferred source to see more of our stories on Google. There are many glorious science-based terms when it comes to surfing. We all talk about swells, of course, the underwater energy ...

So far we have only considered sound in isolation and we have seen that sound has velocity, frequency, wavelength and reduces in intensity in proportion to the square of the distance from the source.

At the interface between two facets of an artificial crystal, sound waves can be transmitted in the opposite direction to that expected, and undergo no reflection. Such wave behaviour could have many ...

The interface between two facets of an artificial material known as a “Weyl phononic crystal” can not only negatively refract an airborne sound wave, it does so without reflecting it at all. This ...

Tuning the instruments that produce some of our most indelible sound waves—guitars, pianos, vocal chords—has become commonplace, expected, easy. Tuning the surfaces awash in those waves, in real time?

Phononic crystals are novel materials that offer exceptional control over phonons, sound and other mechanical waves. Taras Gorishnyy, Martin Maldovan, Chaitanya Ullal and Edwin Thomas report on a ...

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 ...

Diffraction occurs when a wave encounters an obstruction in its path and will change direction, or wrap around it. In ocean waves, we see this occur when a wave encounters an object like a jetty and ...
