The diagram illustrates a wave. Which row is correct?
- Aamplitude of the wave = $1.0\,\text{cm}$, wavelength of the wave = $4.0\,\text{cm}$
- Bamplitude of the wave = $1.0\,\text{cm}$, wavelength of the wave = $8.0\,\text{cm}$
- Camplitude of the wave = $2.0\,\text{cm}$, wavelength of the wave = $4.0\,\text{cm}$
- Damplitude of the wave = $2.0\,\text{cm}$, wavelength of the wave = $8.0\,\text{cm}$
