# What are wavelength, frequency,

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

Solution:

Wavelength : It is the distance between two consecutive compressions or two consecutiv rarefactions.

Frequency : The number of compressions or rarefactions taken together passing through a point in one second is called frequency.

Time Period : It is the time taken by two consecutive compressions or rarefactions to cross a point.

Amplitude : It is the magnitude of maximum displacement of a vibrating particle about its mean position.
