Theory:

A sound wave can be defined by its
  • Amplitude
  • Time period and
  • Frequency

Amplitude:
The amplitude of a sound wave can be defined as the maximum displacement of the particles from their mean position due to the vibrations.
Time period:
The time taken for one complete oscillation of a sound wave is called the time period of the sound wave. 
Timeperiod(T)=1Frequency
 
Frequency:
The number of oscillations an object takes per second is called its frequency.
\(Hertz\) (\(Hz\)) is the SI unit of frequency.
Frequency=TotalnumberofoscillationsTotaltimetaken

\(1\) \(Hz\) \(=\) \(1\) oscillation per second
 
Speed of the sound:
The speed of sound is defined as the distance that sound travels in one second. The letter ‘\(v\)' stands for speed of sound.
It is mathematically represented as,
v=nλ
where '\(n\)' is the frequency and 'λ' is the wavelength.
 
Distance travelled by the sound wave is found by,
Distance(d)=Numberofwaves×Wavelength(λ)
