Specification 6.6.1.2 · Paper 6
The speed at which a wave moves, transferring energy through a medium. Its symbol is and its unit is metres per second (m/s).
Paper 5, Paper 6
The distance travelled by a wave per second, measured in metres per second (m/s).
Revise: Core practical: evaluating wave-measurement equipmentSound travels through a metal rod so quickly that timing its journey with a handheld stopwatch is unsuitable. This core practical investigates how to measure wave speed, frequency and wavelength in a fluid and a solid, and why different equipment suits each measurement.
Convert distances to metres before calculating wave speed in m/s.
