The transmitter sends out EM waves. EM waves are a carrier of energy and are produced by oscillating charges - usually caused by connecting metal to AC power supply. The waves travel through a medium and transfers its energy to the antenna which is basically a metal rod. The energy causes charges in the metal to oscillate at a certain frequency, controlled at the transmitting end. The charges oscillate to produce corresponding EM waves which can be detected/read as signals and turned into sound energy etc...

Why em waves are used to transfer energy using antenna?
hi
How antenna radiate em waves?
The underlying electromagnetic radiation mechanism is illustrated by evaluating the scattered radiated field and its effects on the aperture efficiency by considering the theoretical limits of a radiating conical horn with infinite length
What is the use of antennas?
an antenna is used for transmitting and receiving signals with the use of electro magnetic waves. without the antenna there will not be any communication between one end and the other end. so, antennas play an important role using the EM waves. these em waves take energy from conducting electrons and transmits the information to the other end.
What does the e stand for in EM waves?
EM waves stand for Electromagnetic waves.
What is the energy transferred as em waves?
EM waves or electromagnetic waves is radiant energy.
What does E in EM wave stand for?
EM waves stand for Electromagnetic waves.
Are em waves longitudinal are transverse?
EM waves are both Transverse and Longitudinal.
What should be the position of the antenna with respect to the direction of the transmitted radio waves?
A dish antenna must face the arriving waves.
What should be the position of the antenna with respect to direction of the transmitted radio waves?
A dish antenna must face the arriving waves.
What are Electromagnetic wave transmitted by a radio station called?
Radio stations that broadcast in the AM to FM range transmit EM waves known justly as radio waves (EM waves with frequencies from 30 KHz to 300 MHz, or wavelengths from 10 km to 1 m).
How antenna works?
air waves
