Speed Of Transverse Wave On A Stretched String — the NEET Physics formula with its derivation, variables, validity constraints and worked solver.
Speed of Transverse Wave on a Stretched String Applies to ideal, flexible strings under tension where the stiffness of the string is negligible compared to the tension. Apply Newton's Second Law to a small segment of the curved string. Assume small angles of displacement. Relate the restoring force component of Tension to the centripetal acceleration of the segment. The amplitude of the wave must be small compared to the length of the string. The string is assumed to be perfectly flexible (no stiffness). Gravity effects are usually ignored unless specified. Confusing linear mass density (mass/length) with volumetric density (mass/volume). Assuming the speed of the wave depends on the frequency or wavelength (it depends only on the medium properties T and µ). Believing that increasing the amplitude increases the wave speed.
