How to find frequency

Frequency is defined to be one over the period. So, since the period is the number of seconds per oscillation, the frequency is the number of oscillations per second. Frequency has units of one over seconds, and we call one over a second a hertz. Typical sounds have frequencies in the 100s or even 1000s of hertz.On your frequency chart, it shows 42 people are between these weights. Find the total number in the population. In the example, assume there are 300 people in the school. Divide the frequency by the total population. In the example, 42 divided by 300 equals 0.14, or 14 percent.
