This problem has been solved!See the answerCommunication with submerged submarines via radio waves is difficult because seawater is conductive and absorbs electromagnetic waves. Penetration into the ocean is greater at longer wavelengths, so the United States has radio installations that transmit at 76Hz for submarine communications. What is the approximate wavelength of those extremely low-frequency waves?500 km1000 km2000 km4000 km
