{T}\) In both equations: frequency is measured in Hertz \((Hz)\) and period in seconds \((s)\). If there is a larger number of waves, \(n\), and the time for those waves to pass a point ...

Now I not only understand where the standing waves come from, but that the nodes and anti-nodes map to physical locations on a line that are characteristic of the frequency of the standing wave.

You need to know about these quantities used in waves - what they mean, the symbols used for them and the units used to measure them. Don't get confused with this quantity frequency. It is not a ...
