The relationship between frequency (f), wavelength (λ), and wave speed (v) is given by the equation:
v = λf
Where: v = Wave speed λ = Wavelength f = Frequency
Rearranging the equation, we can solve for the wavelength:
λ = v / f
Substituting the given values: v = 4.0 m/s f = 100 Hz
λ = 4.0 m/s / 100 Hz λ = 0.04 m
Therefore, the wavelength of the wave is 0.04 meters (or 4 centimeters).
