Calculating Resonant Frequencies

Posted by:

This article continues from the last article, Introduction to Resonance. If you need to review standing waves, nodes, and antinodes, you might want to check out that article first. Otherwise, let’s get right down to business.

How to Find Resonant Frequencies

Remember from the last article that standing waves happen when nodes or antinodes line up with the ends of a rope or pipe. Such standing waves create resonance. The lowest frequency that “fits” on a string or in a space ...

Intro to Resonance

Gallopin’ Gertie

One of the first acoustics topics most physics classes cover is resonance. Often, physics teachers will show the video clip below of the collapse of the Tacoma Narrows Bridge (also known affectionately as “Gallopin’ Gertie”) to demonstrate the potential effects of resonance.

While the rippling motion of the bridge seems unreal, the physical principle of resonance is quite real. Gaining an ...
