Just to add this wasn't my proof and I knew it wasn't true. I just couldn't find the mistake. Thanks guys.

Hi all. I found this "proof" and was just wondering if there is an error in it or not, because I couldn't find it. Any ideas? -1/1=1/-1 sqrt(-1/1)=sqrt(1/-1) sqrt(-1)/sqrt(1)=sqrt(1)/sqrt(-1) i/1=1/i i*i/1=i*1/i i^2/1=i/i -1=1 ?

THANK YOU! Resonance is the word I was looking for, you rock :P.

My friend brought up this concept somehow and I know the answer, I just CANT remember what it's called. Sounds silly, I know. But anyways perhaps someone here can help me. What causes the vibration of one guitar string to be the same frequency of another one that has been plucked on that...
