A triangle wave pulse on a taut string travels in positive x–direction with speed v. the tension in the string is F, and linear mass density of string is  $\mu$. At t = 0 the shape of pulse is given by

$\mathrm{y}(\mathrm{x},0)=\left\{\begin{array}{cc}0& \text{ if }\mathrm{x}<-\mathrm{L}\\ \frac{\mathrm{h}(\mathrm{L}+\mathrm{x})}{\mathrm{L}}& \text{ for }-\mathrm{L}<\mathrm{x}<0\\ \frac{\mathrm{h}(\mathrm{L}-\mathrm{x})}{\mathrm{L}}& \text{ for }0<\mathrm{x}<\mathrm{L}\\ 0& \text{ for }\mathrm{x}>\mathrm{L}\end{array}\right.$

Choose the INCORRECT statement(s). (h << L)
