Question
**Question 13** What is the wavelength (in meters) of a 5GHz WiFi radio signal, presuming the speed of light is 300,000 km/sec? - ○ 6 meters - ○ 0.06 meters - ○ 16.67 meters - ○ 1,667 meters **Explanation:** To find the wavelength of a radio signal, you can use the formula: \[ \text{Wavelength} = \frac{\text{Speed of Light}}{\text{Frequency}} \] Given: - Speed of Light = 300,000 km/sec = 300,000,000 meters/second - Frequency = 5 GHz = 5,000,000,000 hertz Calculate: \[ \text{Wavelength} = \frac{300,000,000 \, \text{meters/second}}{5,000,000,000 \, \text{hertz}} = 0.06 \, \text{meters} \] Therefore, the correct answer is **0.06 meters**.

Expert Solution
Step 1

Formula for Wavelength(m) = Speed of Light(m/s) / Frequency(cycles/s)

                                                  

here Frequency = 5000000 Hz

Speed of Light = 300000 Km/sec
