Lecture
This lecture explores the principle of complementarity in quantum physics, which states that a quantum object can exhibit both wave and particle behaviors, but never simultaneously. Through experiments with electrons and light, the instructor demonstrates how the knowledge of a particle's path is incompatible with the observation of interference fringes, highlighting the fundamental nature of this principle. The lecture delves into the implications of the principle of complementarity on our understanding of the dual nature of matter and the limitations it imposes on our ability to simultaneously determine a particle's trajectory and momentum.
