Electromagnetic waves from a computer can go up to ten kilometers also.
That is why computers containing sensitive data like those used for military purpose are effectively shielded with diamagnetic substance, usually a superconductor.
They don't USE any ... none has to be provided in order for the computer to do its job.
But the computer is designed to PRODUCE waves in the visible portion of the spectrum, and to
spew them out from its display, so that the computer operator, game player, or WikiAnswerer
can see what's going on.
These frequencies would be in the microwave range. Anywhere from 2.4 GHz to 5 GHz depending on the type of network. See Related Link.
The wavelength of the electromagnetic visible to the naked human eye is light. Light has wavelengths of 460 to 760 nanometers.
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
From lowest frequency to highest, the electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible light, ultraviolet rays, X-rays, and gamma rays. Heat, or thermal radiation, is also a type of electromagnetic wave, but is not limited to any particular frequency range. Televisions and cell phones use electromagnetic waves in the radio-wave region.
Your comparison attempt is confusing. Water molecules don't have 'waves' by themselves. The ocean has waves, H2O does not. We use the behavior of ocean and sound waves to determine the behavior and makeup of light waves. Humans can only see a portion of the existing electromagnetic spectrum. X-rays and Gamma rays have the shortest wavelengths. Radio waves have the longest.

Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.
It uses radio waves between the range of 2.402 and 2.480 GHz

Conventional lasers do not emit gamma radiation. Lasers use electromagnetic waves in the visible spectrum; this is light that you can actually see. Gamma rays are electromagnetic waves with much more energy and much higher frequency than visible light.
