from Wikipedia, the free encyclopedia

Under quantization refers to a division of a whole into parts, with the differences between these parts can not be arbitrarily small as a continuous variable. Quantization converts function values ​​(the values ​​of physical quantities) into a countable set of numbers, namely all multiples of a quantization level .

In quantum mechanics , this has a special meaning when, for example, one speaks of energy quantization. Here quantization means that the said variable can only assume discrete values, i.e. values ​​contained in a graded value store, instead of being continuously changeable. Experimental physicists James Franck and Gustav Hertz , who received the Nobel Prize in Physics for the Franck-Hertz experiment in 1925 , provided evidence of the quantification of energies that can be absorbed by the electrons in the atomic orbitals .

So far, quantization is known for the following physical objects and quantities: matter , light , energy , charge , momentum , angular momentum , electrical resistance .
