SUMMARY
The tension required for the A string of a violin, with a fundamental frequency of 440Hz, a vibrating length of 32.4cm, and a mass of 0.340g, is calculated to be 85.277N. The velocity of the wave on the string was determined to be 285.12 m/s after correcting the wavelength calculation. The mass per unit length (μ) was confirmed to be 0.001049 kg/m, which is essential for accurate tension calculations. Proper unit conversion and significant figures are critical in achieving the correct result.
