What it is
A short 2009 clip showing a wine glass in front of a loudspeaker being driven at its resonant frequency until it vibrates visibly and shatters, with the key moments shown in slow motion. There is no narration or explanation beyond a one-line description from the uploader.

What do you mean by continuum of frequencies. Also how do I measure these. Also if you need to learn more about natural resonance frequencies than here: [this video]

I am new to learning about the physics of sound, resonance, resonant frequency, and standing waves. Most of the sources I am reading describe the effect of a single frequency on an object when that frequency matches the resonate frequency of the object. For example, in the video in the link below, the man sets the tone generator to 337hz. This is the resonate frequency of the wine glass. At a certain volume the sound breaks the glass. [this video] What I am having a hard time finding is information on the effect of multiple frequencies on a single object. For example: 440hz is a concert pitch A and 528.01hz is the C which is a minor third above the A. What happens to an object whose resonate freq

I'm not sure about the explanation in the video you linked to. The presenter makes it look like the frequency you hear is derived from the air in the glass resonating. While this analysis does a pretty good job at explaining the frequency you would hear if you blow over the top of a test tube, or to a lesser extent a bottle it is not so applicable in the case of a wine glass. The video refers to making the wine glass sound by rubbing you finger around the top of it. In this case you are producing a standing wave where the glass is vibrating rather than the air. This video [this video] at 4:11 give some good slow motion video of the glass vibrating. The vibrating glass does make the air around it

So I was browsing about natural resonant frequencies and how they work, and I stumbled upon this article: [LINK] I watched the video and tried to understand what was going on. Basically they are using a giant sound cannon to blast smog away. I don't understand how this cannon is specifically targeting smog, and if not if that is even what it is supposed to do. I am also working on a similar project and would like to know a few things. Does air have a natural frequency? (I am referring to just any cluster of air and not air as a total because I know that different air may have different natural frequencies) If so how might one find that natural frequency? If not, why not? How does that smog c
