What two properties of electromagnetic waves are used to attach info to radio signals?
By varying the amplitude of a radio wave, you can encode information. That is how AM radio works. By varying the frequency (and hence its wavelength) of a radio wave, you can also encode information. That is how FM radio works.
A good graphical explanation is given at http://cbdd.wsu.edu/kewlcontent/cdoutput/TR502/page21.htm
There are actually FOUR properties. Frequency and amplitude have already been covered. You can also affect the phase of the wave; this isn't very popular because recovering it in the receiver isn't easy, but it's out there. You can also attach information by the presence or absence of the wave. This is how Morse Code is sent.
What else can I help you with?
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.
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 antennaand the receiving antenna, the energy of the radio signal, and the informationencoded in it, travels in the form of electromagnetic waves.
How are electromagnetic waves different to radio waves?
Radio waves ARE electromagnetic waves.
Does a radio wave travel faster than a sound wave?
Radio waves are sound. Therefore, yes, by definition, they travel at the speed of sound.
Can radio waves pass through clouds?
Clouds interfere with radio signals because the density of the cloud can cause static with the radio signal. The air can also interfere with the signal.
How fast are radio signals compared to other forms of electromagnetic waves?
Radio signals travel at the speed of light, which is the fastest speed possible for electromagnetic waves. This means that radio signals travel at the same speed as other forms of electromagnetic waves, such as visible light and X-rays.
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.
Is a radio mechanical energy?
No. Radio waves are a type of electromagnetic waves.
What type of electromagnetic wave is used for TVs?
The type of electromagnetic wave used for TVs is radio waves. Specifically, TV signals are carried on radio frequencies within the electromagnetic spectrum.
How do radio antennas work to receive and transmit signals?
Radio antennas work by converting electrical signals into electromagnetic waves that can travel through the air. When a radio station transmits a signal, the antenna sends out electromagnetic waves. When a radio receiver picks up these waves, the antenna converts them back into electrical signals that can be processed and heard as sound. This process allows for the transmission and reception of radio signals over long distances.
What are Electromagnetic waves used in broadcasting are called?
Electromagnetic waves used in broadcasting are called radio waves. They are used to transmit signals for radio, television, and communication systems.
Does carbon fiber block radio signals?
Yes, carbon fiber can block radio signals because it is an electrically conductive material that can absorb and reflect electromagnetic waves.
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.
What is a sentence for radio energy?
Radio energy is used to transmit signals from one location to another through waves in the electromagnetic spectrum.

Can guitar amps pick up radio signals while being used?
Yes, guitar amps can pick up radio signals while being used due to electromagnetic interference.
