1. **State the problem:** We need to calculate the frequency of a signal given its wavelength is 3.4 meters. 2. **Formula used:** The relationship between the speed of a wave ($v$), its frequency ($f$), and wavelength ($\lambda$) is given by: $$f = \frac{v}{\lambda}$$ 3. **Important rule:** For electromagnetic waves (like radio signals), the speed $v$ is the speed of light, approximately $3 \times 10^8$ meters per second. 4. **Substitute the values:** $$f = \frac{3 \times 10^8}{3.4}$$ 5. **Calculate the frequency:** $$f = 8.8235 \times 10^7$$ 6. **Final answer:** The frequency of the signal is approximately $8.82 \times 10^7$ Hz (Hertz).
