establish the relationship between speed of sound, its wavelength and frequency?

help!!!

Let the speed of sound be **V**. Its wavelength be λ and the frequency be *ν*.

The time period of the wave is given by, T = 1/*ν*

In time T the wave covers a distance of one wavelength λ.

Therefore, speed of sound, **V** = λ/T = *ν*λ

Thus we have, **V** = *ν*λ

Or, Speed = Frequency × Wavelength
