You have a ukulele and you change the strings tension so that it becomes tighter. First the frequency was 431 Hz and after we tightened the string the frequency. how much bigger does the force have t be to get that frequency?
PA*V^2 = F (P = density, A = area)
The Attempt at a Solution
F2 = PA V2=PAf22 * lambda2
F1 = PA V2=PAf12 * lambda2
Then i divided F2 by F1 and I got:
which equals to 1,06. My answer is 6 precent bigger.
So my questions are: can I assume that lambda is going to remain the same? Is my solution correct?
