The atoms in the crystal are to closely spaced for sound waves to be diffracted, only x-rays can do that. However sound can make the crystal vibrate and this can create a piezo electric voltage. Thats how the stylus on some old record players worked; converting the groove vibrations into electricity to be amplified and then sent to speakers to create sound / music.
Neat little demonstration, thanks. Never was taught the interesting science of piezoelectricity in school, but I can recall plenty lectures of how Benjamin Franklin discovered electricity, which always struck me as folklore. After some researching, I now see that people in ancient Greece 1000 years ago had discovered an attraction between amber & fur thanks to piezoelectricity.
Wow! That was great! :) I'm a respiratory therapist and the ultrasonic nebulizer uses this process to generate vapor for breathing treatments and I just thought I'd really like to see some of the science behind why a crystal was chosen for such a purpose - and now I see - it's great! Thanks so much - your video was precise and clear. Perfect!
Is there a limit to the amount of electricity that it can produce, in other words if you continue to flick it forever will there be a point in time where the light will stop flashing?

If I shoot some high decibel sound into a crystal will it do anything like that? Like will the Crystal refract sound like it does with light?

But, will it bend??? Get it? hahahahah

does the material become more dense when a charge is passed through it? Or does it just simply bend.

how much electricity could be produced from a piece if quartz?

if you bend it and hold the bending position, can the light go on without switching off at all?

@mikeakaspike No there is no limit to the amount of electricity that it can produce (unless it breaks eventually)!
