Frequency in Chemistry
In chemistry, frequency refers to the number of occurrences of a repeating event per unit of time. It is a crucial concept in various chemical processes and is particularly important in the study of atomic and molecular spectroscopy.
Frequency in Atomic and Molecular Spectroscopy
In the context of spectroscopy, frequency is used to describe the number of oscillations or cycles of a wave per unit time. In atomic and molecular spectroscopy, the frequency of electromagnetic radiation is directly related to the energy transitions of atoms and molecules.
The relationship between frequency (ν), wavelength (λ), and the speed of light (c) is given by the equation:
ν = c / λ
Where:
- ν = frequency (in hertz, Hz)
- λ = wavelength (in meters, m)
- c = speed of light (approximately 3.00 x 108 m/s in a vacuum)
