What is the correct term when describing the frequency range of 3kHz to 300 GHz?
The term for the frequency range of 3kHz to 300 GHz is known as the radio frequency (RF) spectrum. This spectrum encompasses various types of electromagnetic frequencies used in communication technologies, including radio waves, microwaves, and millimeter waves.
What are the different ranges of the frequency spectrum?
The frequency spectrum is typically divided into different ranges: Audio frequency range: 20 Hz to 20 kHz, encompassing frequencies audible to humans. Radio frequency range: typically ranges from a few kHz to several GHz, used for communication and broadcasting. Microwave frequency range: typically ranges from several GHz to a few hundred GHz, used in microwave ovens and telecommunications. Infrared and visible light range: above microwaves, including the spectrum of visible light and beyond. Ultraviolet, X-ray, and gamma-ray range: higher frequencies with increasing levels of energy and potential harm.
What wave type has a frequency of 23808 GHz?
The wave type with a frequency of 23808 GHz is in the microwave region of the electromagnetic spectrum. This frequency falls in the range of millimeter waves, which are often used in various applications such as wireless communication, radar systems, and imaging technologies.
What is rf input in physics?
In physics, "RF" typically refers to radio frequency. The RF input is a signal or electrical input that operates within the radio frequency range, typically in the range of 3 kHz to 300 GHz. This input is commonly used in communication systems, radar systems, and various electronic devices that transmit or receive radio waves.
Which types of electromagnetic waves are used for radio communication?
Radio communication typically uses electromagnetic waves in the radio frequency range, specifically in the Very High Frequency (VHF) and Ultra High Frequency (UHF) bands. These waves have wavelengths that are suitable for transmitting signals over long distances and are commonly used for broadcasting, two-way radio communication, and cellular communications.
Why is Radio Frequency used in mobile communication?
the frequency used in mobile communication should be greater then 30mhz so cannot be reflected by the ionosphere thats why we are using a frequency of range less ghz so called "radio waves"
What is the down link frequency to earth?
The downlink frequency to Earth, in the context of communication satellites or spacecraft, refers to the frequency at which data is transmitted from the satellite to Earth. The specific frequency used can vary depending on the satellite system and the communication protocol being employed. Generally, downlink frequencies for satellite communication are in the microwave frequency range, typically between 1 to 50 GHz. The choice of downlink frequency is influenced by factors such as transmission range, atmospheric absorption, and regulatory requirements.
What are telephone used for?
Communication.
What is the frequency range used in wireless communication?
2.4GHz is used & OFDM
Is NOT a frequency commonly used for wireless communications?
One frequency that is not commonly used for wireless communications is the extremely low frequency (ELF) range, typically below 3 Hz. This range is unsuitable for conventional wireless communication due to its long wavelength, which requires impractically large antennas and is primarily used for specialized applications like submarine communication. In contrast, frequencies in the megahertz (MHz) and gigahertz (GHz) ranges are widely used for various wireless communication technologies.
What is 3 -30 megahertz?
3 - 30 megahertz is a frequency range within the radio frequency spectrum, commonly used for radio broadcasting, television broadcasts, and various communication systems. It falls in the low frequency range compared to higher frequency bands like microwaves or infrared.
What are the common uses of the 446 MHz frequency band?
The 446 MHz frequency band is commonly used for walkie-talkies, two-way radios, and other short-range communication devices.
What is the correct term when describing the frequency range of 3kHz to 300 GHz?
The term for the frequency range of 3kHz to 300 GHz is known as the radio frequency (RF) spectrum. This spectrum encompasses various types of electromagnetic frequencies used in communication technologies, including radio waves, microwaves, and millimeter waves.
Can someone Describe the various uses of technology to assist communication?
There are many forms of technology that assist communication. These include: the printing press, the telephone, the television, the radio, the computer. The fact that you asked this question on an internet web-site and are receiving my answer from that site is also a form of communication, right? I could add that communication satellites are used to help long-range communication by telephone or other methods.
What frequency range is from 3 GHz to 30 GHz?
The frequency range from 3 GHz to 30 GHz is classified as the Super High Frequency (SHF) band in the electromagnetic spectrum. This range is commonly used for various applications, including radar, satellite communications, and some wireless communication technologies. It is also part of the microwave range, which is crucial for both commercial and military telecommunications.
What is the operating frequency of optical fiber?
In Optical Fiber Communication system 1300-1550 nm range wavelengths are used.. Reason for tis s "In this range only we can acheive low attenuation with zero dispersion"
How is a telegraph like a telephone?
They are both used as a means of communication.
