Within the limits of accuracy of the experiment, positron spin-flipping seems to happen at the same frequency as electron spin-flipping.

ECONOMIST: Are matter and antimatter truly opposites?

The fluids exerted a drag, causing the samples to move to and fro at the same frequency with which the machine jiggled, but with a slight delay.

ECONOMIST: How tree frogs keep their grip

The laser beam in the scanner shoots a steady stream of photons, all of the same frequency, at the plastic.

ECONOMIST: Recycling

Moreover, since the resulting interference pattern also depends on the waves' frequency, the same array can concentrate SAWs in different ways at different frequencies, working the liquid sample in different ways.
