Final answer:
Quantization in physics refers to the property of certain physical entities appearing only in certain discrete values and not having every conceivable value. It is not continuous. Energy quantization is a specific example of quantization, where energy can only exist in discrete values in certain systems.
Step-by-step explanation:
Quantization refers to the property of certain physical entities appearing only in certain discrete values and not having every conceivable value. In other words, it means that something is not continuous. For example, atoms, molecules, and fundamental charges of electron and proton are quantized, meaning they only exist in certain discrete values.
Quantization of energy, a concept in quantum physics, is a specific example of quantization. Energy is quantized in some systems, meaning that the system can have only certain energies and not a continuum of energies like in classical physics. This concept is essential in atomic and nuclear physics, where the discrete energy levels of atoms are observed in atomic spectra.
So, to answer your question, in physics, quantization refers to the discrete values of certain properties.
