Question

The rate at which information can be transmitted on an electromagnetic wave is proportional CZ the frequency of the wave. Is this consistent with the fact that laser telephone transmission at visible frequencies carries far more conversations per optical fiber than conventional electronic transmission in a wire? What is the implication for ELF radio communication with submarines?

Short answer

It is consistent with the facts given.

Step-by-step solution

Define frequency

The number of times a repeated event occurs per unit of time is referred to as frequency.

Explanation

Since visible light has a considerably higher frequency than traditional electrical communication through the wire. Although visible light has a frequency of more than a gigahertz, the frequency of electrical transmission through the wire is just a few gigahertz. As a result, there is increased transmission per optical fiber.

The energy loss is inversely proportional to the wavelength of the wave, as we all know. ELF radio waves have a long wavelength due to their low frequency. So, they are used to reduce energy loss when communicating with submarines.

Therefore, it is consistent with the facts given.
