SUMMARY
The speed of transverse string waves on a piano string of length 1.5 m and mass density 25 mg/m vibrating at a fundamental frequency of 460 Hz can be calculated using the formula v = sqrt(FL/m). By substituting the values, v = sqrt(37.5 * 1.5 / 25) yields the correct speed. Additionally, the relationship v = λf indicates that knowing the fundamental frequency allows for the determination of the wavelength, λ, which is essential for complete wave analysis.
