For an acoustic wave, it's the adiabatic bulk modulus divided by the speed of the wave. For an electric circuit, it's a complex number with real part equal to the resistance and imaginary part equal to the reactance. FTP, name this quantity, whose name comes from a Latin word meaning 'entangle,' often denoted in equations as Z.
