A guitar string with a mass density µ =2 x 10-4 kg/m is L =0.92 m long on the guitar. The stringis tuned by adjusting thetension to T = 73.7 N. 1) With what speed do waves on the string travel? 2) What is the fundamental frequency for the string? 3) Someone places a finge a distance of 0.146 m from the top end of the guitar. What is the fundamental frequency in this case? 4) To down tune the guitar ( so eveything plays at a lower frequency) how should the tension be adjusted? Choose: a) increase the tension b) decrease the tension c) changing the tension will only alter the velocity not the frequency.

Stretched string

A stretched string is a wire which is made up of any metal that must have a larger length compared to its thickness. The ends of the wire are fixed, and when they oscillate or are plucked, it produces two reflected transverse waves of the same frequency and same amplitude. The waves or pulses are traveling in alternate directions and superimpose with one another. This waveform is named standing or stationary waves.
