Problem

At a fixed point in air, the displacement–time graph of a sound wave shows

5

complete oscillations in

0.025\,\text{s}

. If the speed of sound in air is

340\,\text{m/s}

, calculate the wavelength of the wave. (a)

\lambda = 0.68\,\text{m}

(b)

\lambda = 1.7\,\text{m}

(c)

\lambda = 0.017\,\text{m}

(d)

\lambda = 8.5\,\text{m}
