Problem

A sinusoidal wave of frequency

500\,\text{Hz}

travels along a wire. Points

A

and

B

on the wire are

12\,\text{cm}

apart. Point

A

attains maximum positive displacement and,

0.60\,\text{ms}

later, point

B

attains its maximum positive displacement for the first time. Calculate the speed of the wave. (a)

120\,\text{m s}^{-1}

(b)

200\,\text{m s}^{-1}

(c)

133\,\text{m s}^{-1}

(d)

267\,\text{m s}^{-1}
