If there are 30 waves that pass in one second, the frequency of the sound is 30 hertz (Hz).
What is frequency?The number of waves that pass through a fixed point in a given amount of time is described by frequency.
So, if a wave takes half a second to pass, the frequency is 2 per second. The frequency is 100 per hour if it takes 1/100 of an hour.
The frequency is defined as the number of waves (or cycles) that pass through a given point per unit of time. The frequency unit is hertz, which is abbreviated as Hz.
Because 30 waves pass in one second, the frequency is simply 30 Hz in this case.
Thus, 30 hertz frequency is the answer.
