- 2019.11.18: "This has to be one of the absolute BEST videos I have ever seen on resonance for introductory physics. Especially after studying acoustics in my undergrad where I worked on developing a national outreach program for the acoustical society of america, flipping my classroom as a teacher and researching many videos, and now being a graduate physics student studying acoustics again. Well done! I especially love the swing set examples of not resonance and the resonance of the body helping to act as an antenna amplifying the signal of your key fob. I've been asked that question so many times." Cameron Vongsawad - YouTube Comment

Resonance Introduction using 9 Demonstrations (9:38)
Resonance is demonstrated using a “singing rod”, a swing, a goblet, a hollow tube in water, a hollow tube open on both ends, a seashell, a broken speaker, a human body and a key fob, and a shorter “singing rod”. Calculations are performed on the “singing rod”. This is an AP Physics 1 Topic.
