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 ...

This project uses a servo motor and small slinky to demonstrate what a longitudinal wave looks like. Additionally it shows the crests and troughs of that longitudinal wave. It can also be utilized to ...

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 ...
