Gams · Answer 1

Period = (10 seconds) / (2 swings)

Period = 5 seconds

Frequency = (2 swings) / (10 seconds)

Frequency = 0.2 per second. (0.2 Hertz)

Notice that ...

Period = 1 / Frequency,

and

(period) x (frequency) = 1.

These two things are true for every 'periodic' event ... anything that happens over and over and over and over and over. Like wave motion, your heart beat, or going to school.
