Question

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

Solution

Wavelength:- The distance between two consecutive compressions or two consecutive rarefactions is known as the wavelength. Its SI unit is metre (m).

Frequency:- The number of complete oscillations per second is known as the frequency of a sound wave. It is measured in hertz (Hz).

Amplitude:- The maximum height reached by the crest or trough of a sound wave is called its amplitude

  Is there an error in this question or solution?
