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 antenna
and the receiving antenna, the energy of the radio signal, and the information
encoded in it, travels in the form of electromagnetic waves.

What are radio waves and what are they used for?
Radio waves are generated and modulated with the transmitted information at the transmitting station and radiated by its antenna. These radio waves are picked up by the receiver antenna, filtered from all the other transmitted signals, detected and demodulated by the receiver to recover the transmitted information.
Waves used for broadcastig radio signals are called what?
The waves used to broadcast radio signals are called RF waves and these generally lie in VHF and UHF band of electromagnetic spectrum.
The specific electromagnetic wave transmitted by a radio station?
don't no stupid?! that's why i came to find the answer!!!! :O
3 How is digital radio different than the types of radio that came before It?
The way the signal is transmitted and processed. FM radios are transmitted via signal generators and amplifiers on the ground while digital radio like Sirius or AM are transmitted via satellites. The digital signals are sent in packets vs. lower frequency radio waves.
For radio broadcasts sound signals are converted to?
For radio broadcasting, sound waves are converted to electrical waves that are further transmitted. This transformation is done by a device called a transducer, which converts physical parameters into an electrical form (signals).
Cell phone signals are transmitted by?
radio waves radiation
What do baby monitors have to do with Electromagnetic waves?
The monitoring device is a radio transmitter that sends signals to the radio transmitter. Radio waves are a type of Electromagnetic waves.
Why might radio signals also be called radio waves?
A radio signal is essentially an electromagnetic wave in the radio section of the electromagnetic spectrum. Therefore, the radio signal is made of a radio wave.
What are radio waves and what are they used for?
Radio waves are generated and modulated with the transmitted information at the transmitting station and radiated by its antenna. These radio waves are picked up by the receiver antenna, filtered from all the other transmitted signals, detected and demodulated by the receiver to recover the transmitted information.
How are microwaves transmitted?
Microwaves are electromagnetic radiation. They are electromagnetic waves, and they are transmitted like light or radio waves, both of which are forms of electromagnetic radiation. The radiation leaves the microwave source in waves, and this radiation will travel effortlessly through a vacuum, and with a bit of loss through air.
How do signals travel in space?
By use of electromagnetic waves, usually microwaves or radio waves.
Where is wifi on the electromagnetic spectrum?
electromagnetic spectrum is the group of all possible frequencies or wavelengths of electromagnetic radiation
Waves used for broadcastig radio signals are called what?
The waves used to broadcast radio signals are called RF waves and these generally lie in VHF and UHF band of electromagnetic spectrum.
The specific electromagnetic wave transmitted by a radio station?

How do you communicate with others on the moon and earth?
Radio. If you can't talk to them directly by hearing their voices, then it is transmitted by radio.
Explain the basic principle of working of radio?
Radio is the transmission of signals, by modulation of electromagnetic waves with frequencies below those of visible light. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.
What technology is used in a radio?
Wireless Transmission Technology makes Radio devices tune to specific frequency and play the audio being transmitted from Broadcasting Radio Station.Broadcasting Radio Stationbroadcasts audio signals (from Recording Studio)asradio waves to Radio devices within Radiowave signals range.
