The frequency, f of an oscillating disturbance is equal to number of times (cycle) everysecond the disturbance passes from the one extreme position to other and back tooriginal position. The number of times (cycles) per second is called Hertz. Basically,the frequency in pure tone sound wave namely pitch of the tone.
