How did he generate and detect EM waves?
He generated electromagnetic waves by accelerating charges back and forth rapidly in an antenna. He detected the waves by using a similar antenna that would convert the electromagnetic waves into electrical signals.
How does an antenna pick up waves?
An antenna picks up waves by converting electromagnetic fields into electrical signals. When radio waves interact with the antenna, they induce an alternating current within the antenna which is then processed by the connected circuitry to extract information or energy from the waves. The size and shape of the antenna determine which frequencies it is most sensitive to.
What does the e stand for in EM waves?
EM waves stand for Electromagnetic waves.
Are em waves longitudinal are transverse?
EM waves are both Transverse and Longitudinal.
How does an antenna work to receive and transmit radio signals?
An antenna works by converting electrical signals into radio waves for transmission and vice versa for reception. When an electrical current flows through the antenna, it creates electromagnetic waves that can travel through the air. These waves carry information in the form of radio signals. The antenna's design and length determine the frequency of the radio waves it can send and receive.
Why em waves are used to transfer energy using antenna?

Why antenna is a sensor of EM waves?
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...
What type of energy transfers information from a radio station to the radio?
RF stands for Radio Frequency, magnetic waves radiate out of the transmitting antenna and are picked up or recovered by the receiving antenna at the receiver.
What is the importance of antenna in a wireless communication system?
For wireless communication systems, the antenna is one of the most critical components. A good design of the antenna can relax system requirements and improve overall system performance. An antenna is the system component that is designed to radiate or receive electromagnetic waves. In other words, the antenna is the electromagnetic transducer which is used to convert, in the transmitting mode, guided waves within a transmission line to radiated free-space waves or to convert, in the receiving mode, free-space waves to guided waves.
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 is the purpose of an antenna coupler?
1.transmission and reception 2.impedence matching 3.sensor to em waves 4.suppressing
Is the receiving antenna radiate radio wave during reception?
A receiving antenna does "re-radiate" some of the power it receives, but not all. Some of the power it receives proceeds into the receiver ... which is the only way we detect the signal being received by the antenna.
Do sound waves radiate?
yes
How does an antenna pick up waves?

When radio waves interact with the antenna, they induce an alternating current within the antenna which is then processed by the connected circuitry to extract information or energy from the waves.

What does E in EM wave stand for?
EM waves stand for Electromagnetic waves.
Difference between isotropic antenna and omnidirectional antenna?
The isotropicantenna by definition has a radiation pattern that is a perfect sphere. The omni driectional antenna is characterized by a radiation pattern resembling a doughnut.
