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.
