Perhaps your students would benefit from seeing a Chladni Plate device in action using different frequencies, built by your very good self of course
Same concept is used in a wave tank, which I definitely utilized when I was teaching physics.Perhaps your students would benefit from seeing a Chladni Plate device in action using different frequencies, built by your very good self of course
If you or any other Paranormalis member would like to know where to obtain small inexpensive 200 watt stereo amplifiers, they can be found for less than 20 dollars on Ebay, and of course you can have three Chladni Plates operating at the same time!!...
I use two of those small amplifiers on my indoor Delta Time Antenna showing on my profile picture, top left of this posting, and they have constantly been used in my own experiments for several years....Front and Rear Pictures of my amplifiers below ..

I disagree Hartey, the wave tank can only perform certain types of a basic water wave, compared to the highly complex Chladni Plate shapes that change continuously into even more complex shapes by using different audio frequencies...Do you feel incapable of building a Chladni Plate device? ..Same concept is used in a wave tank, which I definitely utilized when I was teaching physics.

I thought chlandni plate, was a type of pasta and now I want a big plate of pasta tonight. Just ignore me, I'll go away, but I gotta laugh. Thnaks
Yeah. No real point in it - the idea is to actually teach the physics and YOU try to get high school kids to write equations for those complex standing wave patterns.I disagree Hartey, the wave tank can only perform certain types of a basic water wave, compared to the highly complex Chladni Plate shapes that change continuously into even more complex shapes by using different audio frequencies...Do you feel incapable of building a Chladni Plate device? ..
