At points X and Y, wave generators create water waves with identical wavelength. At Z, the waves arriving from X have the same amplitude as those arriving from Y. The distances XZ and YZ are shown. If the wave generators work in phase, the oscillation amplitude at Z is zero. What might the wavelength of the waves be?
- A$2\,\text{cm}$
- B$3\,\text{cm}$
- C$4\,\text{cm}$
- D$6\,\text{cm}$
