The tin can phone is a staple of longitudinal wave demonstrations wherein a human voice vibrates the bottom of a soup can, and compression waves travel along a string to reproduce the speaker in ...

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 ...

Waves are said to be transverse if they oscillate perpendicularly to their direction of propagation, and longitudinal if they oscillate parallel to that direction. Light is a transverse wave, whereas ...
