In general, people believe that whatever a microwave oven does to foods cooked in it doesnt have any negative effect on either the food or them.
In our modern technological age, microwaves are used to relay long distance telephone signals, television programs, and computer information across the earth or to a satellite in space.
But the microwave is most familiar to us as an energy source for cooking food.
Every microwave oven contains a magnetron, a tube in which electrons are affected by magnetic and electric fields in such a way as to produce micro wavelength radiation at about 2450 Mega Hertz (MHz) or 2.45 Giga Hertz (GHz).
By comparison, microwaves from the sun are based on principles of pulsed direct current (DC) that dont create frictional heat; microwave ovens use alternating current (AC) creating frictional heat.
A microwave oven produces a spiked wavelength of energy with all the power going into only one narrow frequency of the energy spectrum.
