Problem

A displacement–position graph taken at an instant shows that the distance between two consecutive compressions of a sound wave is

0.68\,\text{m}

. The corresponding displacement–time graph for a particle of the same wave gives a period of

1.7\,\text{ms}

. The speed of the wave is (a)

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

(b)

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

(c)

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

(d)

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