Transition from Quantum to Particle

This paper explores the transition from quantum wave behavior to classical particle dynamics, establishing a fundamental link between kinetic energy, momentum, and Planck's constant. We demonstrate that, under specific conditions, the quantum wave of De Broglie collapses into a particle when the wavelength mathematically disappears, leading to a characteristic velocity threshold given by:v = h / mThis velocity represents a lower bound at which quantum effects dominate, and beyond which the system exhibits classical behavior. The analysis provides a theoretical foundation for understanding quantum decoherence, wavefunction collapse, and the transition from quantum to classical mechanics.
