how do you find wave speed in a string. The Speed of a Wave on a String. The speed of a pulse or wave on a string under tension can be found with the equation v sqrtfracF_Tmu label168 where F_T is the tension in the string and ยต is the mass per length of the string.
The speed of transverse waves on a string is determined by two factors i the linear mass density or mass per unit length m and ii the tension T. V f l. When the taut string is at rest at the equilibrium position the tension in the string F T is constant.
Speed Wavelength x Frequency.
If numerical values are not entered for any quantity it will default to a string of 100 cm length tuned to 440 Hz. V f l. The equation for wave speed can be written to solve for wavelength or frequency if the speed and the other value are known. The speed of transverse wave set up in the string depends upon numerous factors like tension applied T mass per unit length of the string etc.
