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.
The _______________ of a wave is a direct measure of its energy. a. wavelength b. normal c. medium d. amplitude 12. The frequency of a wave represents the a. wave amplitude divided by the period of the wave. b. wave crest in relationship to the wave trough. c. number of waves that pass a certain point in a given time. d. loudness of the sound.
