Are there theories for the different sound in different volume of beaker?

[s0610038]

so, apart from doing experiment with the frequency topic, what topic will you guys advice me to do?

My assessment is to develop an experiment to prove a physics theory, but the main thing is the experimental way must be designed and not used before.

Thanks for all your advices! really! thanks so much!

Would this work? Pick one of the ideas or claims you've seen in this discussion, explain the reasoning and do an experiment to see if it your experimental results agree with the explanation.

Does that sound like it will work for you? While we should not lay out the entire project for you, we can help you further along a path you choose.

You said you had equipment to measure sound. Does it tell you the frequency of the sound? Will it tell you all the frequencies in complicated sound?

If you want a more simple experiment /investigation around this topic, why not investigate resonance in a long vertical tube (a resonating air column) where you adjust the length of the column by varying the level of water in it? You could use a loudspeaker, driven from a signal generator and your ear as a detector - looking for peaks in resonance (frequency against apparent loudness). You could then determine the wavelength of the sound in the air column and also the speed of the sound in the tube. The theory is much more straightforward and more appropriate to your level of understanding.
You don't have to worry about it having been done before. ALL this stuff has been done already, many times! No one would seriously expect you to be doing 'cutting edge' Science.
