Answer: Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 GHz to as low as 9 kHz .
Read moreWhat is RF and why is it important?
The Rf value represents the difference between the migration of the developing solvent and the compound being evaluated in Thin-Layer Chromatography (TLC) . The Rf value serves as a simple measurement of the relative binding of the compound of interest under the experimental conditions.
Read moreWhat RF frequencies are harmful to humans?
Scientific evidence suggests that cancer is not only linked to mobile phone radiation and that other factors also may be involved in its development. Most mobile operators use from radiofrequency waves in the range up 300 MHz to 3 GHz that can be harmful for human health (1).
Read moreWhat is radio frequency used for?
Radio frequencies are used in communication devices such as transmitters, receivers, computers, televisions, and mobile phones , to name a few. Radio frequencies are also applied in carrier current systems including telephony and control circuits.
Read moreWhat is radio frequency and how does it work?
How radio frequency works. Radio frequency is measured in units called hertz (Hz), which represent the number of cycles per second when a radio wave is transmitted . One hertz equals one cycle per second; radio waves range from thousands (kilohertz) to millions (megahertz) to billions (gigahertz) of cycles per second.
Read moreWhat is radio frequency signal?
A radio frequency (RF) signal refers to a wireless electromagnetic signal used as a form of communication , if one is discussing wireless electronics. Radio waves are a form of electromagnetic radiation with identified radio frequencies that range from 3kHz to 300 GHz.
