Question on: SS1 Physics - Modern Physics

Energy quantization in quantum theory refers to the idea that energy levels of atoms and particles are discrete and can only take specific values. This is in contrast to classical physics, where energy is considered continuous and can have any value. In quantum theory, energy is quantized due to the wave-particle duality of matter and the existence of stationary states. The energy of a system can only exist in specific quantized levels, and transitions between these levels occur when particles absorb or emit energy in discrete amounts, called quanta.
