(1) The maximum displacement of a particle on either side of its mean position is called the amplitude of the wave.
(2) Time taken by the particle of a medium to complete one vibration is called the time period.
(3) The number of vibrations made by the particle of a medium in one second is called the frequency.
(4) The frequency of a wave is different than the frequency of the source producing it.
