This is done by microwave antennas,since signals can be sent in form of waves.Those types of waves are commonly known as electromagnetic waves i.e waves that result due to the electric and magnetic fields.

∙ 14y agoWhen electric charges are at rest then only electric field exists around that stationary charge. When the charge is in uniform motion, then apart from electric field a magnetic field is also produced. But when the charge is accelerated then it produces a disturbance even in the free space ie vacuum. This disturbance will be just like disturbances produced on the surface of water as stones are continuously dropped into the calm pond. Just like crests and troughs there will be electric field changing from positive maximum to negative maximum. Simultaneously magnetic field also varies in the same manner. Hence electro magnetic waves are produced and getting propagated through space. This is transmission.
When such electro magnetic waves reach a particular coil or some other metallic substances that would induce the electrons in it to flow to and fro and thus alternating electric current is induced. This is reception.

What is the reason for ultrasonic waves not being in the form of electromagnetic waves?
Ultrasonic waves are high frequency sonic waves. They're sound, which is mechanical energy. Electromagnetic waves are waves of electromagnetic energy, like radio waves or light. Mechanical energy is different from electromagnetic energy, hence the reason for ultrasonic waves not taking the form of electromagnetic waves.
Sound is not part of the electromagnetic spectrum because?
because sound waves are not a electromagnetic waves because they need a medium for travel....hence electromagnetic spectrum is based on the electromagnetic waves ..like radio waves , micro waves , etc....
The energy of visible light transported by electromagnetic waves are what type of waves?
electromagnetic waves are longitudinal (like a slinky).
Which is not a type of electromagnetic wave?
Sound waves aren't an electromagnetic wave. So aren't seismic waves. So aren't waves in the ocean, in your hair, or waves bye-bye.
What kinds of waves make up the electromagnetic spectrum?
Those are called electromagnetic waves.
Is radiation a energy that's transmitted from one place to another by electromagnetic waves?
Yes, radiation is energy that is transmitted from one place to another by electromagnetic waves...hope i could help :)
The waves which cannot be transmitted in waveguide are?
The Transverse electromagnetic(TEM) wave cannot be transmitted within a wave guide.
How is electromagnetic spectrum related to electrons?
No direct relation; electromagnetic waves are transmitted by photons. However, electromagnetic waves are often caused by the acceleration of electric charges, and those charges are usually electrons. Also, electromagnetic waves are emitted and absorbed when an electron (in an atom) changes to another energy level.
Where is wifi on the electromagnetic spectrum?
electromagnetic spectrum is the group of all possible frequencies or wavelengths of electromagnetic radiation
Why are radio signals not transmitted directly by electromagnetic waves?
The question's meaning is mysterious. Radio signals AREelectromagnetic waves,specifically those in the band of frequencies/wavelengths known as "radio waves".That's exactly what is physically transmitted. Between the transmitting antennaand the receiving antenna, the energy of the radio signal, and the informationencoded in it, travels in the form of electromagnetic waves.
Can light be transferred across empty space?
Yes. Electromagnetic waves, like light, can travel through a vacuum, they need no medium in order to be transmitted. Unlike sound waves, which are compression waves what rely on matter in order to be transmitted.
How is information transmitted from one place to another?
By carrier pigeon, a runner, the mail service, electric wires, electromagnetic waves, sound waves.
Theory of electromagnetic radiation?
James Clerk Maxwell came up with the Theory of Electromagnetic Radiation.He stated that, "When electrically charged particle moves under acceleration, alternating electrical and magnetic fields are produced and transmitted in the forms of waves called electromagnetic waves or electromagnetic radiation."This is the Theory of Electromagnetic Radiation.
Information in transmitted in terms of energy transfer in a telephone?
Information is usually transmitted in terms of either radio waves or acoustic energy in a telephone. Machines such as the fax are usually used.
What type of enerygy travels in waves?
All Electromagnetic Energy travels in Waves...as does Sound. Quantum Science also has a "Particle" Theory for the transmission of Electromagnetic Energy. That is why you hear about Light being transmitted as PHOTONS (particles).
Are the sun's rays mechanical waves or electromagnetic waves?
Electromagnetic waves
How can astronauts communicate with earth if sound does not travel in a vacuum?
Signals are transmitted by some other means - in this case, electromagnetic waves.
