Glass Shattering Frequency
I am trying to find some info. for my teacher. Can you
please tell me what sound frequencies shatter glass??
lets say you take a good crystal class and tap it gently with a hammer. It
makes a high pitched ting sound. You can now imagine the reverse. Use sound
at this same frequency, back at the glass. It will make the glass vibrate,
maybe enough to break the glass. So they are the same things, in reverse.
Hammering glass makes sound, or same frequency sound back at the glass makes
it seem like it was "hit" with a force, an imaginary hammer.
