A group of international researchers have developed a way to use sound to generate different types of wave patterns on the ...

Ocean waves have long been seen as having huge potential as a source of renewable energy. Waves produce an estimated 50 ...

It confirms that sound behaves as a wave phenomenon, with characteristics such as bending around obstacles and creating interference patterns. The relationship between speed, frequency ...

he can produce a diverse array of patterns as sound waves bounce off the sides of the dish, repeatedly cycling back and forth. Where waves meet and add up, they create nodes. When ripples cancel ...

Sound is a vibration that travels through air as a wave. These waves are created when an object moves back and forth, compressing and decompressing air molecules. The frequency of these vibrations ...

“Second sound is the hallmark of superfluidity, but in ultracold gases so far you could only see it in this faint reflection ...

Well, it's all to do with the strength of the vibration. A weak vibration makes a gentle sound wave which doesn't travel very far. Be quiet! A vibration with lots of energy makes a very powerful wave.
