The A string of a violin is 34 cm long between fixed points with a fundamental frequency of 440 Hz and a mass per unit length of 6.2×10−4 kg/m . What is the wave speed in the string? What is the tension in the string? What is the length of the tube of a simple wind instrument (say, an organ pipe) closed at one end whose fundamental is also 440 Hz if the speed of sound is 343m/s in air?...

12) The diddley bow is an instrument which consists of a single-string tensioned between two points on a board, often using a glass bottle (see figure) for a bridge and a way to amplify the instrument's sound. The speed of sound in air is v = 343 m/s. a) What tension (in N) is required in a string with mass-per-unit-length u = 1 g/m to produce a fundamental frequency of G, or 49 Hz, if the length is L =...
