SUMMARY

The origin of quantization is fundamentally linked to boundary conditions in quantum mechanics. Specifically, an electron in a hydrogen atom exhibits quantized energy levels due to the constraints of bounded motion, while a free particle possesses a continuous energy spectrum due to unbounded motion. This distinction is crucial for understanding the behavior of particles under different potential interactions. The discussion emphasizes that the nature of the energy spectrum—discrete or continuous—depends on whether the motion is bounded or unbounded.

What is the origin of quantization?

For example, electron of hydrogen atom has quantized energy level. But free particle has continuous energy level.

Interaction with another particle or any potential acting on particle makes such quantization?

It's the boundary conditions.

Almost universally, an energy spectrum is discrete if only bounded motion is possible continuous if only unbounded motion is possible, and mixed otherwise.
