Equation
       
    Name Characteristic Impedance
 
    Equation Z = T v = ρ ⁢ v
 
    Definition of terms Z = impedance, T = tension (transverse force), v = velocity, ρ = density
 
    Comments The impedance of a transverse wave on a string is equal to the force divided by the velocity. Since the tension T = ρc2, the impedance is also equal to the density times the velocity
