#### Reflectance and Transmittance of a Yielding String Termination

Consider the special case of a reflection and transmission at a

*yielding termination*, or ``bridge'', of an ideal vibrating string on its right end, as shown in Fig.C.28. Denote the incident and reflected velocity waves by and , respectively, and similarly denote the force-wave components by and . Finally, denote the velocity of the termination itself by , and its force-wave reflectance by

*bridge velocity transmittance*is given by

*force transmittance*is given by
