Homework Help: The resonance of air in a wine glass

  1. Jan 7, 2010 #1
    1. i have this science fair project coming up, and we had an idea to use acoustic levitation here is a link (http://www.thenakedscientists.com/HTML/content/kitchenscience/exp/acoustic-levitation/") the problem is that i don't know what the resonance of air is in a wine glass. it says that i need a certain frequency to make the resonating effect, and it will cause the air pressure in the glass to increase, and as a side note, what intensity should i use to be able to levitate a piece of paper.



    2. I don't really have equations because this is a high school project, and i don't know why, but my teacher does not recommend using equations as that will make the experiment more difficult.



    3. I really have no idea, sorry
