how to calculate wave speed 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 µ is the mass per length of the string. Lets start with a small length of string and suppose that the change in y from one end to the other is.

Use the velocity equation to find the actual tension. I want to know how is the velocity calculated by this equation is the same as velocity by kinematics v Dd Dt. Calculate the frequency of the first second and third harmonics.
Where we neglect the term involving x x 0 since the pulse is within D x of x 0 and we neglect the first order derivative in comparison with the first term since x 0 2 y d x 2 x 0 D x y d x.
Use the velocity equation to find the speed. When the taut string is at rest at the equilibrium position the tension in the string. Wave Speed on a String under Tension To see how the speed of a wave on a string depends on the tension and the linear density consider a pulse sent down a taut string Figure. The tension would be slightly less than 1128 N.
