It is equal to one-half the length of the vibration path.]]> 2017-11-02 18:13:30 UTC https://padlet.com/304007/1z011ry5atgn/wish/203057602 304007 https://padlet.com/304007/1z011ry5atgn/wish/203057679 Wavelength is also measured in metres (m) - it is a length after all. The frequency, f, of a wave is the number of waves passing a point in a certain time.]]> 2017-11-02 18:13:39 UTC https://padlet.com/304007/1z011ry5atgn/wish/203057679 304007 https://padlet.com/304007/1z011ry5atgn/wish/203057803 The speed (or sometimes you might see it called velocity) of a wave, v, is how far the wave travels in a certain time. ]]> 2017-11-02 18:13:52 UTC https://padlet.com/304007/1z011ry5atgn/wish/203057803 304007 https://padlet.com/304007/1z011ry5atgn/wish/203057925 Do not conclude that sound is a transverse wave that has crests and troughs. Sound waves traveling through air are indeed longitudinal waves with compressions and rarefactions.
