How does a computer use electromagnetic waves

Web802.11 WLANs use radio waves having frequencies of 2.4 GHz and 5 GHz, which means that the signal includes 2,400,000,000 cycles per second and 5,000,000,000 cycles per second, respectively. Signals operating at these frequencies are too high for humans to hear and too low for humans to see. WebYour computer, whether it is a desktop or a laptop, emits EMFs. The closer you are to the computer, the stronger the electromagnetic field. Electromagnetic fields (EMFs) don’t only come from your computer screen. The electronics inside your computer generate a powerful EMF. Close Proximity of EMFs
