The resonant frequency of the wood pieces varies according to their size.

The presence of other ions may raise the resonant frequency by up to 50%.

It had been found that resonant frequencies could be created by running at certain speeds.

Two of these are required to set the bandwidth and resonant frequency.

I was wondering, what is the resonant frequency of copper?

Another simple system, a mass hanging from a spring, also has a resonant frequency.

Every musical instrument, including your voice, depends on resonant frequencies.

Therefore, the resonant frequency of the plate, which depends on its size, will not change much, either.

A network analyser is needed to view the resonant frequency.

In the case of this power conversion system, the spring also changes the resonant frequency.
