Learn the skill

Frequency is the number of complete cycles per second. Divide cycles by elapsed seconds. Frequency is not amplitude or loudness. These are paper records; no loud sound or equipment is needed.

Worked example

A model completes 24 cycles in 3 s. Its frequency is 8 cycles/s, or 8 Hz.

A schematic repeating wave shows 4 complete cycles about a center line. Count complete cycles over time. No physical length or time scale is assigned to this drawing.
