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 ...

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 ...

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 ...

Imagine a wave that could achieve faster than light communications; one that could travel through any material including Faraday cages, and wirelessly beam power to receivers. Nikola Tesla ...

The sensation felt by our ears is called sound. It is a form of energy which makes us hear. We hear several sounds around us in our everyday life. We know that sound travels in the form of wave. A ...

Sound is something most people take for granted. Our environment is full of noises, which we have been exposed to from before birth. What is sound, how does it propagate, and how can it be quantified?

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 ...
