I have a question concerning the speed of propagation of a travelling wave along a cable. If I have a cable and I move one end in a direction perpendicular to that of the length of the cable, it will generate a wave/pulse which will propagate along the cable with some speed. I imagine this speed depends on a number of properties of the cable: tension, elasticity, stiffness, density and also perhaps the viscosity of the fluid that the cable is resting in. I can't, however, seem to find a formula to describe the speed of wave propagation based on these factors - has this been determined and can anyone point me in the right direction? To give you some context, the cable Im concerned with is a cable in a biological sample. I've observed the propagation of waves of velocity along the cable and was hoping that extracting their speed could give me some insight into the properties of the biological tissue. Thanks for any help!
