What are wavelength, frequency, time period and amplitude of a sound wave ?

Text Solution

Verified by Experts

(i) The minimum distance in which a sound wave repeats itself is called its wavelength. In most simple words, it is the length of one complete wave.
(ii) The number of complete sound waves (or cycles) produced in one second is called frequency of the sound wave.
(iii) The time required to produce one complete sound waves (or cycle) is called time-period of the sound wave.
(iv) The maximum displacement of the particles of the medium from their original undisturbed positions, when a sound wave passes through the medium, is called amplitude of the sound wave.
