Question

what are wavelength, frequency, time-period and amplitude of a sound wave?​

Answer 1

$\underline{ \underline \mathfrak \blue{wave \: length}}$

The minimum distance in which a sound wave repeats itself is called it's wavelength. in most simple words, it is the length of one complete wave. ‏‏‎ ‎‏‏‎ ‎

$\underline{ \underline \mathfrak \pink{frequency}}$

The number of complete sound waves(or cycle) produced in one second is called frequency of the sound wave.

$\underline{ \underline \mathfrak \color{purple}time \: period}$

The time required to produce one complete sound wave (or cycle) is called time-period of the sound wave.

$\underline{ \underline \mathfrak \color{blue}amplitude}$

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.
