Explanation:

Wavespeed V = 350 m/s

Frequency = 140 Hz.

Wavelength = ?

Since, the wavelength is the distance covered by the wave in one complete cycle. It is measured in metres, and represented by the symbol λ.

So, apply the formula:

Velocity (V) = Frequency F x wavelength λ

350m/s = 140Hz x λ

λ = 350m/s / 140Hz

λ = 2.5 m

Thus, the wavelength of a wave is 2.5metres
