• A transverse sinusoidal wave of amplitude $a$, wavelength $\lambda$ and frequency $n$ is travelling on a stretched string. The maximum speed of any point on the string is $v/10$, where $v$ is the speed of propagation of the wave. If $a={{10}^{-3}}\,m$ and $v=10\,m{{s}^{-1}}$, then $\lambda$ and $n$ are given by
