All electromagnetic radiation can be used for communication, up to frequency of,

let's say, 3 x 1015 Hz (down to wavelength of, say, 100 x 10-9 m), in the ultraviolet.

Past that, higher frequencies (shorter wavelengths) are difficult to generate, modulate,

and control, are more hazardous to human exposure, and are absorbed in the atmosphere,

so they're not too practical for communication.

Why acoustic waves concept is used instead of electromagnetic waves in under water communication?

Acoustic waves are used in underwater communication because they can travel long distances in water due to lower absorption and scattering compared to electromagnetic waves. Electromagnetic waves, such as radio waves, are quickly absorbed by water, limiting their range and effectiveness for underwater communication. Acoustic waves are also less affected by obstacles and can penetrate through water more effectively.
