The principle of uncertainty was introduced by Werner Heisenberg in 1927. This principle asserts that the more precisely the position of a particle is known, the less precisely its momentum can be known, and vice versa. It is a cornerstone of quantum mechanics and has profound implications for the behavior of particles at microscopic scales.
If \( \lambda \) and \( K \) are de Broglie wavelength and kinetic energy, respectively, of a particle with constant mass. The correct graphical representation for the particle will be:
