Problem

A sound wave travels through air such that three successive compressions occur at positions

x = 0.00\,\text{m},\; 0.85\,\text{m}

and

1.70\,\text{m}

. At a particular location, the displacement–time graph shows

8

complete oscillations in

0.020\,\text{s}

. Determine the speed of the wave. a)

170\,\text{m/s}

340\,\text{m/s}

680\,\text{m/s}

40\,\text{m/s}
