Microwave
Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter; with frequencies between 300 MHz (100 cm) and 300 GHz (0.1 cm). Different sources define different frequency ranges as microwaves; the above broad definition includes both UHF and EHF (millimeter wave) bands. A more common definition in radio engineering is the range between 1 and 100 GHz (wavelengths between 300 and 3 mm). In all cases, microwaves include the entire SHF band (3 to 30 GHz, or 10 to 1 cm) at minimum. Frequencies in the microwave range are often referred to by their IEEE radar band designations: S, C, X, Ku, K, or Ka band, or by similar NATO or EU designations.
Radio
Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.

Books are the friends of solitude. They develop individuality and freedom. In solitary reading a man who is seeking himself has some chance of finding himself. … Radio, on the other hand, is now the chief agent of imperialism. It does not purify the spirit of man, does not, like the book, bring him back to the sanctuary of solitude, but throws him to the lions, subtly preparing his mind for the blood and chains of public sacrifice.
Georges Duhamel, In Defense of Letters (1937), E. Bozman, trans. (1939), p. 42

First radio, then television, have assaulted and overturned the privacy of the home, the real American privacy, which permitted the development of a higher and more independent life within democratic society.
Allan Bloom, The Closing of the American Mind (New York: 1988), p. 58

All this, I said, just as today was the case with the beginnings of wireless, would be of no more service to man than as an escape from himself and his true aims, and a means of surrounding himself with an ever closer mesh of distractions and useless activities.
