Answer:
Wavelength of the wave, λ = 0.3 m
Step-by-step explanation:
It is given that,
The speed of the wave, v = 3 m/s
The frequency of the wave, f = 10 Hz
We know the relationship between the frequency, wavelength and the speed of the wave. Mathematically, it can be written as :

or




Hence, the wavelength of the wave is 0.3 m
