WebWavelength is usually denoted by the Greek letter lambda (λ); it is equal to the speed ( v) of a wave train in a medium divided by its frequency ( f ): λ = v / f. The Editors of Encyclopaedia Britannica This article was most recently revised and updated by Erik Gregersen. WebIn the air, the speed can be calculated by dividing the time it takes for sound to travel between two points. v = d Δ t Here, ‘d’ is the distance travelled in metres, while ‘ Δt’ is the time difference. The speed of sound in the air at average conditions is used as a reference for objects moving at high speeds by using the Mach number.
