What are wavelength, frequency, time period and amplitude of a sound wave?
The distance between any two consecutive compressions or rarefactions is called wavelength .
It is denoted by lamba. (λ)
Its SI unit is metre (m)
The number of oscillations made in one second is called frequency.
It is denoted by nu (ν).
Its SI unit is hertz(Hz).
The time required to produce one complete wave is called the time-period .
It is denoted by t.
Its SI unit is second (s).
The maximum displacement of a vibrating object from its central location is called amplitude.
It is denoted by A.
Its SI unit is metre(m).
