Look the diagram for it is =)
A Bottle filled with varying water volume to change air volume in the bottle =)
the opening of the bottle is kept under a speaker which can be connected to a laptop for varying frequency of the sound ;)
Keep a microphone near the opening and it should be connected to the laptop as well just to give tell you when the amplitude of frequency was highest ;)

Dug ; what do you think ?

Btw, that's correct method to calculate the volume of air in the bottle.
But, the microphone should be positioned at the bottom of the bottle !
$~SauD~$
$~SauD~$
think about?

i don't think so =) cause, the water MIGHT absorb the sound :)
and if you try, blow up different voices in a bottle of water ;) You will hear some sound back :D The most sharp or high pitched mean high amplitude :)

But since you positioned the microphone near the loudspeaker, it will record the sound directly from the loudspeaker !
$~SauD~$
$~SauD~$
well tell me how does Ultrasound thing works? :)
when the loudspeaker sends out voice it stops and then the mic. can start working :)

:p

Are you sure about this then ?
$~SauD~$
$~SauD~$
I guess so ;) well this is practicals so you can have many different answers and concepts O_O
