Radio is the transmission of signals, by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.

What is the working principle of rectenna?
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
What is EMF used for?
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)
What are the specifications of the tin hing u2812-093-045e transformer used in rca rp5430 radio clock?
9v and 4.25v, measured from a working transformer inside the clock radio.
What is working principle of electronic energy meter?
The working principle of an electronic energy meter is a device that measures the electronic energy consumed (usually in KWh). It is often incased in glass and has a disk that rotates that measures the amount of power (product of current and voltage) the flows through the meter. The rotation is then integrated over time either by mechanical dials or an electronic digital counter to determine the total energy used.To simplify reading, many modern ones also contain a type of radio transponder that can be interrogated remotely from the meter reader's vehicle so he/she no longer has to find, read, and write down the value on every meter on his route.
What is the principle of radar?
The basic idea behind radar is very simple: a signal is transmitted, it bounces off an object and it is later received by some type of receiver. This is like the type of thing that happens when sound echo's off a wall. However radars don't use sound as a signal. Instead they use certain kinds of electromagnetic waves called radio waves and microwaves. This is where the name RADAR comes from (Radio Detection And Ranging). Sound is used as a signal to detect objects in devices called SONAR (Sound Navigation Ranging).

What is the best citizens band radio for the money?
Cobra has really improved their products over the years. For a basic, working man's CB radio, I'd recommend either the Cobra 25 or Cobra 29.... just get the basic model, and avoid things such as Nightwatch and the automatic squelch.
What is the scientific principle of television?
Manipulation of the radio magnetic spectrum.
What is the principle of AM Radio?
alot of people like to talk about up to date but not so popoular issues on AM radio.
Where do you find the fuse to the clock as the LED was no longer working in doing so the radio stopped working you have checked all of the fuses that seemed to be linked to the radio?
Your radio operates on one fuse, so if your display wasn't working, but the radio still worked, your radio is fried. Replace it.
How a triode works as basic amplifier?
A triode works as a basic amplifier by the use of radio waves. The radio waves produce a heat that is amplified.
