The graph illustrates how the displacement of a particle changes with time as a progressive wave moves through it. What are the wave’s frequency and amplitude?
- Afrequency $100\ \text{MHz}$, amplitude $5\ \text{mm}$
- Bfrequency $200\ \text{MHz}$, amplitude $5\ \text{mm}$
- Cfrequency $100\ \text{MHz}$, amplitude $10\ \text{mm}$
- Dfrequency $200\ \text{MHz}$, amplitude $10\ \text{mm}$
