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. We normally use a time of one second, so this gives frequency the unit hertz (Hz), since one hertz is equal to one wave per second. Don't get confused with this quantity frequency. It is not a distance travelled by waves, nor is it a speed, although it is linked to both of these quantities.
SI unit of amplitude and wavelength is meter (m). SI unit of frequency is Hz (s -1).Posted by Somnath (MeritNation Expert) on 29/2/12. This conversation is already closed by Expert.he SI unit for wavelength is meters (m). S I unit of frequency is hertz (Hz). There is no special SI unit of amplitude.
