When an electrical field changes sign, some of the energy will radiate into space. When the sign reverses the field will change again.
Thus radiated into space at approx the speed of light will be a series of electromagnetic waves.
These waves can also carry modulation - a characteristic of the wave may be varied. In the simplest form, the amplitude of the radio wave (commonly known as the carrier) may be varied by applying a speech signal for example.
Several other modulation styles are also available, and I'll just name them, rather than describing them. Phase Modulation, Frequency Modulation, Pulse Modulation.
In addition, the polarization of a wave may be varied.
What else can I help you with?
The main difference between a radio wave and a light wave is?
The difference between a radio wave and a x-ray is the fact that x-rays have a much higher frequency. Since higher frequency means more energy in electromagnetic waves, x-rays can be used for purposes such as taking photos of things inside the body. Radio waves are at a lower frequency and have a much longer wavelength. They are used in radio, television, and communication.
What wave viabrates faster radio wave or microwaves?
Microwaves ARE radio waves, with frequencies above 3 GHz.
What is one example of a radio wave?
-- AM radio -- FM radio -- TV (non-cable) -- TV (satellite) -- police radio -- firetruck radio -- ambulance radio -- sheriff's radio -- highway patrol radio -- taxi radio -- garage-door opener -- pilot's communication -- pilot's navigation -- Blue tooth -- cellphone -- wireless Internet in the house -- iPhone -- Wifi around town -- microwave cooking -- microwave communication -- weather radar -- cellular phone -- GPS signals
What is the use of radio communication?
it is used for the communication
Is radio wave can cut out electrics?
Radio waves themselves do not cut out electronics, but they can interfere with electronic devices if the frequency of the radio wave overlaps with the device's operational frequency. This interference can cause malfunctions or disruptions in communication, but it won't physically cut off power. In some cases, strong radio signals can induce currents in nearby circuits, potentially affecting their operation. However, this is more about interference than cutting out electrics.
What is the cause of error in wireless communication?
normally, it is where a radio wave is interfering with the communication wave that you are sending out (I think).
How can radio wave laser technology be utilized for communication and data transmission?
Radio wave laser technology can be used for communication and data transmission by converting radio waves into laser beams, which can then be transmitted over long distances with high speed and accuracy. This technology allows for more efficient and secure communication, making it ideal for applications such as satellite communication, wireless networks, and data transfer in various industries.
What type of wave has the longest wavelength and the lowest frequency?
The type of wave that has the longest wavelength and lowest frequency is a radio wave. These waves are used for communication and broadcasting due to their ability to travel long distances.
The main difference between a radio wave and a light wave is its?
The main difference between a radio wave and a light wave is their wavelengths. Light waves have shorter wavelengths compared to radio waves. Additionally, light waves are part of the electromagnetic spectrum that can be seen by the human eye, whereas radio waves are typically used for communication and have longer wavelengths.
What is a wave with the longest wavelength and lowest frequency?
The type of wave with the longest wavelength and lowest frequency is a radio wave. These waves have frequencies ranging from about 3 kHz to 300 GHz and are used for various forms of communication, including radio broadcasts and mobile phone signals.
What electro magnetic wave has the lowest frecuencies?
Radio waves as low as 10kHz are used for communication with submarines.
How do you make radio wave in Doodle God?
Void+electricity
How do you make radiation in doodle god?
Radio wave + radio wave will make radiation.
Are electromagnet wave is radio wave?
yes, electromagnetic wave is a radio wave
What kind of wave is a radio wave?
A radio wave is a kind of electromagnetic wave.
WHAT wave can represent a radio wave?
A radio
What is frequency of a satellite wave?
I never heard of a "satellite wave". If you mean the radio waves used by satellites for communication - well, like all radio waves used for such purposes, there is probably a large range of waves they can use.
