One of the 61.0cm -long strings of an ordinary guitar is tuned to produce the note B3 (frequency 245 Hz) when vibrating in its fundamental mode.
a) Find the speed of transverse waves on this string. (found it.. it's 299m/s)
b) If the tension in this string is increased by 2.5% what will be the new fundamental frequency of the string? (Can't figure out)
