The correct Answer is:
To find the frequency of the radio waves transmitted by the broadcasting station, we can use the relationship between velocity (V), frequency (f), and wavelength (λ). The formula is given by: \[ V = f \times \lambda \] Where: - \( V \) is the velocity of the wave, - \( f \) is the frequency of the wave, - \( \lambda \) is the wavelength of the wave. ### Step-by-Step Solution: 1. **Identify the given values**: - Wavelength \( \lambda = 422.54 \, m \) - Velocity \( V = 3 \times 10^8 \, m/s \) 2. **Rearrange the formula to solve for frequency**: \[ f = \frac{V}{\lambda} \] 3. **Substitute the known values into the equation**: \[ f = \frac{3 \times 10^8 \, m/s}{422.54 \, m} \] 4. **Perform the calculation**: - First, calculate the division: \[ f = \frac{3 \times 10^8}{422.54} \] - Using a calculator, we find: \[ f \approx 710,000 \, Hz \] 5. **Convert the frequency to kilohertz (kHz)**: - Since \( 1 \, kHz = 1000 \, Hz \): \[ f \approx 710 \, kHz \] ### Final Answer: The frequency of the wave is approximately **710 kHz**. ---
