The answers given before includes the information that radio is best used when it is spread in all dirrections whereas microwaves are best use when dirrected in one particular direction

"Radio" or "Radio Waves" are energy expended in the form of electro magnetic radiation. More specifically the term "Radio" refers to a specific frequency pattern of that radiation. This is how Radio broadcasting works. "Microwaves" are a said to be all radio frequency between 300Mhz and 30 Ghz. Thus microwave is a specific class of "Radio Wave". For more in depth explanations research the theroys of Heinrich Hertz.
Radio waves - in the microwave section of the electromagnetic spectrum.
Much higher frequency...Normally the microwave signal is focused by a parabolic disk into a beam that can be pointed ...This sends most of the power in one direction.
a microwave requires a much higher frequency
A: AM radio is an Amplitude Modulation transmission . Meaning it has fix frequency but it is modulated by the signal. FM Frequency Modulation the frequency is modulated by the signal
They are very similar in the transmission of the signal. The production of the media is different because of the aspect of vision in TV.
RF means radio frequency or relativity low range of frequency microwaves however are into the top range of the spectrum or very hi frequency.
Scientists group electromagnetic waves into categories according to their wavelength. Technically a radio wave has a longer wavelength then a microwave but that's the only fundamental difference. They are both electromagnetic waves.
A short-wavelength radio wave. An electromagnetic wave that is somewhere in between regular radio waves and infrared radiation.
The primary difference is that the microwave signal is of a much higher frequency than an AM signal, if that AM signal is speaking to AM broadcast radio. In general, AM, or amplitude modulation, is not generally used as a modulation technique on microwave frequencies because there are other ways to put a signal on a microwave carrier that allow more information to be transmitted. AM is "low frequency" RF, while FM is a bit higher on the radio frequency spectrum, and microwaves are further on up.
The difference between a Philips portable radio and a standard radio are that a Philips radio is battery powered, while a regular radio is electrically powered.
