Microwaves are said to be Electromagnetic waves with frequency 300 Mhz to 300 Ghz. If so, then, is the CPU of my computer running at 2Ghz, emitting some sort of microwave ? Is the microwave cooking tiny drops of water around ? (I say so, because, if the CPU is running at 2GHz, currents must be pulsing at 2Ghz, and that might create EM wave at 2Ghz). Also, if I make some resonant electric Circuit to oscillate at 500 Thz, will I see some 'Red Lights' . Also, if I static charge my plastic pen by rubbing against my hair, and then 'Wave' this charged pen at round 3 hz, will I be creating Radio Waves at 3hz ? Thanks for reading.
