Hey guys, in the experiment i did i had to vary the length of the wire and locate the fundamental frequency. after doing that i had to Plot L against 1/f1 f1 being fundamental freq, and L being length of wire...
what does this graph represent its gradient, its intercepts..
any help would be greatly appreciated

ok the equation relating fundamental frequency of a transverse wave on a string is
which rearranges to
where T is the tension in the string, l is the length of the string and is the mass per unit length of the string.
you should be able to find a derivation of this in an alevel physics text. (well it is in mine, but then again I am using a book from the 1980's !)
your graph should therefore be a straight line through the origin with a gradient of

Blimey - I thought sonometers went out with the ark.
thanks, really appreciate it
