Quantization of energy is a crucial principle in quantum physics, which asserts that the energy of certain physical systems can only take on specific, discrete values or levels.
This concept challenges classical physics, where energy was thought to be continuous and freely divisible. In contrast, in the quantum world, energy levels are "quantized" into distinct, non-divisible units.
One of the most well-known examples is the quantization of electron energy levels in atoms, as described by Niels Bohr's atomic model. Electrons orbiting the nucleus can only exist in specific energy states, or "shells."
Quantization of energy has far-reaching implications in understanding the behavior of particles and the development of quantum mechanics, revolutionizing our understanding of the microscopic world.
