Radio waves, sounds waves arn't electromagnetic waves.
radio waves.
Solar flares emit electromagnetic waves.The electromagnetic wave interrupted cellular phone communications.Satellites can be damaged by electromagnetic waves.
A camera does not make use of electromagnetic waves in its operation. Instead, it captures light, which is part of the electromagnetic spectrum, but it does not rely on the transmission or reception of electromagnetic waves like a loudspeaker, radar station, or radio set, which all utilize electromagnetic waves to function.
WiFi uses electromagnetic waves in the microwave band, around 2.4 GHz or 5 GHz.
Computers do not use waves, they use a digital signal. Unlike a wave, a digital signal is composed of a sequences of high and low voltages. These voltages remain at a constant voltages for both high and low. For example, a high voltage may be 5v while a low voltage may be -5v. Computers are designed to interpret these as 1s and 0s, or binary - the language of computers.
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.
Radio waves ARE electromagnetic waves.
Electromagnetic waves are transferred by electromagnetic radiation.
