Introduction

A certain transverse wave is described by

y$($x$,$t$)=$Bcos$[2\backslash$pi $($xL$-$t$\backslash$tau $)]$y$($x$,$t$)=$Bcos$[2\backslash$pi $($xL$-$t$\backslash$tau $)],$

where BB $=5\mathrm{.}80$ mmmm$,$ LL $=28\mathrm{.}0$ cmcm$,$ and $\backslash$tau $\backslash$tau $=3\mathrm{.}00\backslash$times $10-2$ ss$.$
