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 moreWhy do we need frequency bands?
A frequency band may represent one communication channel or be subdivided into many . Allocation of radio frequency ranges to different uses is a major function of radio spectrum allocation.
