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 ...

Negative refraction of elastic waves has been studied and experimentally demonstrated in three- and two-dimensional phononic crystals, but Bragg scattering is impractical for low-frequency wave ...

sound waves cause air particles to vibrate back and forth ripples cause water particles to vibrate up and down Waves cause a disturbance of the medium through which they travel. This allows them to ...

Michael Hall receives funding from the Australian Research Council and the Foundational Questions Institute. We see them at the beach. They’re behind every sound and light show and the miracle of ...

A wave is defined as a continuous movement that transmits energy through matter or space.Energy can be conveyed from its source by a wave. The material through which the wave goes does not move with ...

Waves transfer energy from one place to another. Light from the Sun travels through space and through the atmosphere, transferring energy to the Earth and other planets. Sound travels from a ...
