Wave speed of a stretched string
Actual value of v = ?/k is determined by the medium
as wave passes, the “particles” in the medium oscillate
medium has both inertia (KE) and elasticity (PE)
dimensional argument: v= length/time LT-1
inertia is the mass of an element ?=mass/length ML-1
tension F is the elastic character (a force) MLT-2
how can we combine tension and mass density to get units of speed?
