Physics - Wave on String Question with Solution | TestHub

General equation of plane prograssive wave is given by $$y=a\sin (kx+\omega t)$$ Given equation $$y=0.0015\sin (62.4x+316t)\text{ ...(ii) }$$ Comparing Eqs. (i) and (ii), we get $$\begin{array}{rl}k& =62.4\\ \frac{2\pi }{\lambda }& =62.4\\ \lambda & =\frac{2\pi }{62.4}=0.1\text{ unit }\end{array}$$
