a sound wave travels at 330 m/sec and has a wavelenght of 2meters. calcuate the frequency and period



Answer :

AL2006

The frequency of any wave is  (speed) / (wavelength).

 Frequency = (330 m/s) / (2m)  =  165 per second = 165 Hz.

Period = 1 / frequency  =  1 / (165 per second) = 0.0061 second
