Answer:
The wavelength of Radio 4, which broadcasts on a frequency of 198 kHz, is approximately 15.152 meters.
Step-by-step explanation:
The wavelength of a radio wave is calculated by dividing the speed of light (approximately 3 x 10^8 meters per second) by the frequency of the wave.
To calculate the wavelength of Radio 4, which broadcasts on a frequency of 198 kHz, we can use the following equation:
wavelength = (speed of light) / (frequency)
wavelength = (3 x 10^8 m/s) / (198 x 10^3 Hz)
wavelength = 15.152 meters
So the wavelength of Radio 4, which broadcasts on a frequency of 198 kHz, is approximately 15.152 meters.
