Frequency
What is Frequency?
Frequency is the number of complete wave cycles per unit time, measured in hertz (Hz), where 1 Hz = 1 cycle per second. In electromagnetic radiation, frequency (ν) is related to wavelength (λ) and the speed of light (c) by c = νλ. Higher frequency corresponds to higher photon energy (E = hν, where h is Planck's constant). Frequency is fundamental to spectroscopy and quantum chemistry.
