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 ...

The questions in this quiz are suitable for GCSE physics students studying longitudinal waves, transverse waves, electromagnetic waves, radio waves, microwaves, infrared and visible light and ...

Researchers have identified unexpected dynamic properties of a type of light wave called evanescent waves. These surprising findings contrast sharply with previous knowledge about light and photons. A ...

A research team has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does. The findings shattered ...
