Problem

Along a stretched string, a wave of amplitude

2\,\text{mm}

and frequency

50\,\text{Hz}

travels in the +

x

direction. At

t=0

, the particle at

x=0

is at its maximum positive displacement, while the particle at

x=0.30\,\text{m}

is simultaneously at its maximum negative displacement. (a) Determine the wavelength of the wave. (b) Hence write the complete displacement equation

y(x,t)

in the sine form.
