Problem

In a transverse wave represented on a

y

–

x

graph at an instant, the greatest positive displacement recorded is

+5\,\text{cm}

and the greatest negative displacement is

-5\,\text{cm}

. The point at

x=10\,\text{cm}

is found at a displacement of

+5\,\text{cm}

. (a) State the amplitude of the wave. (b) Is the particle at

x=10\,\text{cm}

located at a crest, a trough or neither?
