A system proposed by the U.S. Navy for underwater submarine communication, called ELF (for extremely low...
In the 1990s the Russian and American navies developed extremely low frequency communications networks to send messages to submerged submarines. The frequency of the carrier wave of the Russian network was 82 Hz, while the Americans used 76 Hz. What was the ratio of the wavelengths of the Russian network to the American network? Be sure to express your answer in decimal form. To calculate the actual underwater wavelength of the transmissions in either network, what additional information would you...
