The diagram illustrates two waves X and Y. Wave X has amplitude $8\,\text{cm}$ and frequency $100\,\text{Hz}$. Determine the amplitude and frequency of wave Y.
- Aamplitude $2\,\text{cm}$, frequency $33\,\text{Hz}$
- Bamplitude $2\,\text{cm}$, frequency $300\,\text{Hz}$
- Camplitude $4\,\text{cm}$, frequency $33\,\text{Hz}$
- Damplitude $4\,\text{cm}$, frequency $300\,\text{Hz}$
