Answer 1

What is the longest wavelength of audio signals to be transmitted in communication

system

Answer 2

Answer:

300Hz is the longest wavelength of audio signals to a distance of 1000 kilometers. Majorly, in Submerged submarines 300 Hz wavelength of audio signal are used.

In land, we cannot transfer high amount of wavelength signals because the transmitter requires more area and also require more power to transmit. For long wavelength signals we require low frequency signals which will damage the environment.
