Question

what is meant by quantization of physical quantity ?

Answer 1

Quantization is the concept that aphysical quantity can have only certain discrete values. Electrical charge, energy, light, angular momentum, and matter are all quantized on the microscopic level. ... Also, the energy levels of electrons in atoms arequantized.

Answer 2

Quantization is the concept that a physical quantity can have only certain discrete values. Electrical charge, energy, light, angular momentum, and matter are all quantized on the microscopic level. They do not seem quantized on the macroscopic scale because the size of the steps between each possible value is so small. For example, matter is quantized because it is composed of individual particles that cannot be subdivided; it is not possible to have half an electron. Also, the energy levels of electrons in atoms are quantized. The electron's energy can have only certain values, and all intermediate values are prohibited. Mathematically this quantization arises from treating the electron's orbit as a standing wave, such that the orbit's circumference is equal a whole number of wavelengths.
