Question:

A sound wave travels a distance of 1020 m in 5 minutes. If the length of the three successive crests is 15 m, then calculate the wave speed.

Periodic wave

For a periodic wave, its wave speed {eq}v {/eq}, wavelength {eq}\lambda {/eq} and frequency {eq}f {/eq} are related according to

{eq}v = \lambda f. {/eq}
