The frequency of the sound emitted by the lioudspeaker is 1020 Hz. Calculate the wavelength of the sound wave in air in cm where its velocity is 340 m/s.

Answer :

Frequency = 1020Hz

velocity = 340m/s i.e. 34000 cm/s

Wavelength = velocity / frequency

                      = 34000 / 1020

                      = 100 /3

                       = 33.33cm
