... The Particle Description of Light Electromagnetic radiation is absorbed by matter only in whole numbers of photons. In order for an electron to be ejected from the metal surface, it must be struck by a single photon possessing the minimum amount of energy required to knock the electron loose. This ...

Atomic Spectroscopy
... Beer's Law states that the light absorption is proportional to the number of absorbing species in the sample. Effectively for AA, this means that the amount of energy (light) absorbed is proportional to the concentration of atoms in the atomizer. Thus if a concentration of atoms 'c' produced an abso ...

Ultraviolet–visible spectroscopy
Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent (near-UV and near-infrared [NIR]) ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, molecules undergo electronic transitions. This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.
