Frequency and period

AMPLITUDE AND WAVELENGTH Wavelength refers to the length of a wave from one peak to the next . The amplitude or height of a wave is measured from the peak to the trough. The wavelength is measured from peak to peak. Wavelength is directly related to the frequency of a given wave form.

amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position . It is equal to one-half the length of the vibration path.

Volume (amplitude ) – shown by the height of the waves displayed. The larger the amplitude of the waves, the louder the sound. Pitch (frequency) – shown by the spacing of the waves displayed . The closer together the waves are, the higher the pitch of the sound.
