How Can We Use Conductors to Receive EM from Space?

In summary, conductors receive electromagnetic waves from space through induction, and the most common type of conductors used are metal antennas. Conductors differ from insulators in their ability to freely move electric charges, making them better equipped to receive EM waves. They can receive all types of EM waves from space, but may require additional equipment and proper design and placement to effectively receive and transmit them.

the concept of wave guide is built that the fielt can't get through the conductiong surface??

but we use conductors to get the EM from space how this could happen can sny one give the ans

Pretty simple really,

you see at high frequencies the currents are on the surface of the conductors. It's called the "skin effect".

ya its right but is it true in both the case antenna and guide. please clarify me.

ya its right tyger but is it true in both the case antenna and guide. please clarify me.
 

1. How do conductors receive electromagnetic waves from space?

Conductors receive electromagnetic waves from space through a process called induction. When an electromagnetic wave passes through a conductor, it creates an alternating current that can be detected and converted into usable energy.

2. What types of conductors are typically used to receive EM waves from space?

The most common conductors used to receive EM waves from space are metal antennas, such as dish antennas or dipole antennas. These are often used in satellite communication systems and radio telescopes.

3. How do conductors differ from insulators in terms of receiving EM waves?

Conductors are materials that allow electric charges to move freely, while insulators are materials that resist the flow of electric charges. This means that conductors are better equipped to receive and transmit EM waves compared to insulators.

4. Can conductors receive all types of EM waves from space?

Yes, conductors can receive all types of EM waves from space, including radio waves, microwaves, infrared waves, visible light, ultraviolet waves, X-rays, and gamma rays. However, different types of conductors may be more efficient at receiving certain types of waves.

5. Can conductors be used to receive EM waves from space on their own, without any additional equipment?

No, conductors alone cannot receive and transmit EM waves from space. They require additional equipment, such as amplifiers and receivers, to convert the electromagnetic energy into usable signals. The design and placement of the conductor also play a crucial role in its ability to receive EM waves effectively.
