Problem

In air, a sound wave shows successive compressions at positions

0.30\,\text{m}

and

0.90\,\text{m}

on a displacement–distance description. At the same place, the time between two successive compressions on a displacement–time record is

0.002\,\text{s}

. Calculate the speed of the sound wave. (a)

150\,\text{m/s}

(b)

300\,\text{m/s}

(c)

600\,\text{m/s}

(d)

1200\,\text{m/s}
