Frequency and period

Solution: (a) Amplitude – The maximum displacement of a wave on either side of its mean position is called Amplitude . (b) Frequency – Number of oscillations made by a wave in one second is known as frequency.

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.
