How does the frequency of an electromagnetic wave compare with that of the electrons it sets into oscillation in a receiving antenna?

The frequency of an electromagnetic wave must be very high to release electrons. The electrons that it releases are set into oscillation in a receiving antenna must by definition have a lesser frequency.

What happen to sound in terms of frequency as an object moves away from you?
The frequency, as observed by the receiving end, will be less than the frequency at which the wave was emitted.
What energy transformation occur at the receiving station?
electromagnetic energy to sound energy
What type of energy is radiant energy?
It is electromagnetic radiation, which has a wide variation of frequency or wavelength, from long radio waves up to gamma radiation, and including visible light. Heat energy is radiated in the infra-red region, because that includes the frequencies which cause heating in receiving objects.
Is it possible to transmit electricity as electromagnetic waves?
Well, when you transmit something as an electromagnetic wave, it is no longer an electric current, since an electromagnetic wave doesn't involve movement of charges. However, you can convert electrical energy into an electromagnetic wave, transfer that, and then convert it back to an electric current at the receiving end.
What is skywave propagation?
the propagation in which transmission and receiving of signals takesplace through the sky waves which having the lower frequency
How television signals receiving?
by using electromagnetic
Is covalent bond only sharing electrons or receiving?
A covalent bond is only the sharing of electrons. An ionic bond involves the losing and receiving of electrons.

What energy transformation occur at the receiving station?
electromagnetic energy to sound energy
What are the electrons doing in the two kinds of bonding?
in an ionic bond the electrons are gaining or receiving electrons. in a covalent bond 2 atoms are sharing electrons
What is mien by carrier frequency?
High range of frequency that carries the message signals in transmission of data.after receiving the signals, the detector seperate the message and carrier .
What type of energy is radiant energy?
It is electromagnetic radiation, which has a wide variation of frequency or wavelength, from long radio waves up to gamma radiation, and including visible light. Heat energy is radiated in the infra-red region, because that includes the frequencies which cause heating in receiving objects.
What does electro negativity of an element indicate?
How much an element is attracted to receiving valance electrons. The more electronegative, the more it needs electrons.

How radio communicate works?
Radio communication works on radio signals that are "beamed" into the air on a certain frequency. Frequency is a certain wavelength or band. The receiving equipment has to be set to receive the signal on the same frequency.
Is there any way to pick up a frequency to know someone has a cell phone on them?
In order to LISTEN to them: The frequency spectrums in whcih the commercial communications carriers operate are public record and commercially available radio receiving equipment is available. Therefore, if you kinow what frequency you want to listen to, simply tune it in. HOWEVER - don't be too surprised if some/much/all of it may be 'scrambled. In order to DETERMINE if a person has a cellphone on their person - yes. There are commercially available detectors which will pick up the presence of an electromagnetic field in the presence of a cellphone.
What is modulation index for frequency modulation?
It varies depending on how strong you want the signal to come through on the receiving end.
