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 ...

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 ...

In the lab students determine the factor affecting the frequency of a pendulum. In the lab students determine the factor affecting the frequency of a pendulum and relate to simple harmonic motion.

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 ...

Types of Waves: In Physics, waves are a fundamental phenomena that describes the transmission of energy and information through a medium of an empty space. These waves are characterised by their ...
