A charged particle oscillates about its mean equilibrium position with a frequency of \(10^9 \text{ Hz}\). The electromagnetic waves produced:
| (a) | will have frequency of \(2×10^9 \text{ Hz}\) |
| (b) | will have frequency of \(10^9 \text{ Hz}\) |
| (c) | will have wavelength of \(0.3\) m |
| (d) | fall in the region of radiowaves |
Choose the correct options:
| 1. | (a), (b), (c) | 2. | (a), (c), (d) |
| 3. | (b), (c), (d) | 4. | (c), (d) |
