You cannot use a rectifier to go from DC to AC. You need an oscillator.
Radio waves are electromagnetic waves that carry energy. When these waves are absorbed by the radio's antenna, they induce electrical currents in the circuitry of the radio. This process allows the radio to convert the energy from the radio waves into sound, enabling us to hear broadcasts. However, radio waves themselves do not heat; it is the conversion of that energy into electrical signals that allows the radio to function.
AM transmitters convert sound into amplitude modulated radio waves which am radios convert into electrical pulses which speakers convert into air waves that are converted into sound by our eardrum.
Don't know the answer? Then you suck!
Radio sound is heard through the use of radio waves, which are electromagnetic waves that can carry information from one point to another. These waves are transmitted from a radio station and received by a radio receiver, such as a radio or smartphone, which then converts the waves into sound waves that we can hear.
this is usually referring to a type of rectifier, not the waves themselves.
The principle of radio waves is that change of current strength will generate waves. Advantage of this special phenomenon information can be loaded on the waves through modulation.when radio waves arriving receive side through space the change of electromagnetic field generated by waves will lead to current in conductor To extract information from change of current and reach the purpose of messaging.
Electromagnetic waves, such as radio waves, transmit information from one antenna to another. These waves carry the signal that contains the information being transmitted, like radio broadcasts, Wi-Fi signals, or cellular communication.
no, mechanical waves are not radio waves
A radio produces sound, and therefore sound energy. The radio waves, however, are electromagnetic energy, not sound. The function of a radio is to convert that electromagnetic energy into sound energy.
Radio waves ARE electromagnetic waves.
Transverse. Radio waves are electromagnetic waves, which are transverse.
No. Radar waves are one category of radio waves. Think of all the radio waves that are all around you right now . . . AM radio, FM radio, police and fire radio, highway patrol radio, taxi radio, television picture and sound radio waves, cellphone radio waves, garage-door-opener radio waves, bluetooth radio waves, WiFi waves, microwaves ... and you can't see any of them ! Radar waves can easily be there in the group.
