I still do not know the first node is sometimes
very close to the prong (for example 2 cm) and
sometimes far away, for example, 18 cm.

1a) Observe the length of this "fractional loop", i.e. the distance from
the prong to the first node.

1b) Express this as a percentage of the length of a full loop, i.e. the
node-to-node distance.

1c) Plot this as a function of frequency. See if any regularities appear.

2) What does wave mechanics predict?
