A radio wave is strictly a carrier of information. The modulation is necessary to convey the information, speech, music, data, etc. Sometimes a radio wave can carry information by its presence or absence. If the radio wave is present, it means one thing. If it is not present, it means another.
What else can I help you with?
How do radio waves get from the radio station to your car radio?
Radio stations use a broadcasting antenna to transmit electromagnetic waves at literally hundreds of thousands of watts. This transmission is modulated, (tuned), at a specific frequency between 87 and 108 Mhz.
Which has a higher frequencies am radio waves or fm radio waves?
FM radio has the higher frequency which is why it sounds better. AM is a lower frequency but can travel further because the waves bounce off
What three types of signals are carried by radio waves?
Radio waves carry three main types of signals: analog signals, digital signals, and modulated signals. Analog signals transmit continuous variations in amplitude or frequency, while digital signals convey information in discrete binary form. Modulated signals, which can be either amplitude modulation (AM) or frequency modulation (FM), are variations of these basic types that encode information onto a carrier wave for efficient transmission over distances.
How does radio communication device work?
A radio communication device works by converting sound waves into electrical signals, which are then modulated onto a carrier wave for transmission. The modulated signal is broadcasted through an antenna, propagating through the air as electromagnetic waves. At the receiving end, another antenna captures these waves, and the device demodulates the signal back into sound waves, allowing for clear audio communication. This process enables two-way communication over varying distances, depending on the device's power and frequency used.
What is the frequency of radio wave?
Fm radio waves travel at various frequencies between 87.5 MHz and 108.0 MHz
What does fm and am stand for?
AM-Amplitude modulated FM-Frequency modulated Explanation: The frequency and amplitude refer to the width and height of wavelengths in the radio waves that are used to transmit the signal. FM is usually a better signal than AM because the frequency of the waves is less distorted than amplitude.

What two properties of EM waves are used to attach info to radio signals?
The only properties of EM waves that you can control are amplitude and frequency. (Wavelength is related to frequency in a simple numerical way.) Amplitude-modulated radio (AM) is what you listen to between 550 and 1700 on your dial, and Frequency-modulated radio (FM) is what you listen to between 88 and 108. There are also slick high-tech methods of attaching one stream of information to the amplitude and different information to the frequency at the same time.
What is a form of transmission in which signals are modulated as radio frequency analog waves that use different frequency ranges?
Broadband, the most common network data transmission system in use today.
What type of information is encoded in radio waves?
Radio waves can contain various types of information, such as audio signals for radios, television broadcasts, data transmissions for wireless communication devices, and radar signals for navigation and tracking purposes. The information is modulated onto the radio waves in the form of amplitude, frequency, or phase modulation.
What electromagnetic wave have the lowest frequency?
Radio Waves.
What radio waves?
Radio waves are electromagnetic waves occurring on the radio frequency portion of the electromagnetic spectrum.
How are radio and television waves added to em radio waves?
by changing the amplitude or frequency of the radio waves.
What is the frequency range of radio waves that can penetrate human body?
The frequency range that the radio waves can penetrate the human body is between 1Hz and 10 KHz. This frequency of the radio waves is however not dangerous.
How are radio waves and television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
How are radio and television waves added to em waves?
by changing the amplitude or frequency of the radio waves.
What has highest frequency gamma rays infared waves or radio waves?
Gamma rays have the highest frequency among gamma rays, infrared waves, and radio waves.
