To calculate the wavelength (\(\lambda\)) of a signal, you can use the formula:
\[ \lambda = \frac{c}{f} \]
where:
- \(\lambda\) is the wavelength,
- \(c\) is the speed of light in a vacuum (approximately \(3 \times 10^8\) meters per second), and
- \(f\) is the frequency in hertz (Hz).
Given that the frequency (f) is 350 MHz, we first convert MHz to Hz:
\[ 350 \text{ MHz} = 350 \times 10^6 \text{ Hz} = 350000000 \text{ Hz} \]
Now we can calculate the wavelength:
\[ \lambda = \frac{3 \times 10^8 \text{ m/s}}{350000000 \text{ Hz}} \approx 0.857 \text{ meters} \]
Thus, the wavelength of a signal with a frequency of 350 MHz is approximately 0.857 meters.
So, the answer is 0.857.
