alot of people like to talk about up to date but not so popoular issues on AM radio.
What is the name of the radio engineer that is a principle inventor of T.V.?"
Resonance

In principle, any type of radio service can be carried on in any part of the radio spectrum.But it happens that the commercial AM radio broadcast service is situated quite low in thespectrum ... between 0.55 and 1.7 MHz. As such, it has the longest wavelength that you'relikely to run into.There are certainly services that operate at lower frequencies ... time signals to the so-called"atomic" clocks, submarine communication, legacy navigation systems etc. But of the two choiceslisted in the question, AM radio is by the far the lower frequency / longer wavelength.

Manipulation of the radio magnetic spectrum.

A radio scanner or an optical scanner? You need to specify

Autoradiography is a photograph showing the distribution of a radioactive substance in a chosen specimen. The photographic plate is exposed to radioactive emissions from the specimen. Another term for this principle is radio autograph.
No. As you might guess from the name, radar uses radio waves. Radio waves, in turn, are a type of electromagnetic wave - in other words, in principle similar to light waves.
assuming you mean electromotive force: emf is the main principle behind power transformers. emf also comes in the form of radio waves, which are used for radio transmission (obviously)
AM radios are based on the principle of sound waves being sent through the air. If the AM radio station has static, you may wish to move to a new area where reception is better.
rectenna is nothing but RECTifying anTENNA and this converts radio waves to electricity.the radio waves may be anything such as microwaves etc., by what does this rectenna works? this is only through the mesh of diodes and dipoles
