👉 The seminar on "Light Particles" delves into the fundamental nature of light, exploring it as both a wave and a particle phenomenon, a concept central to quantum mechanics. It begins by discussing the historical context, from Newton's corpuscular theory to Einstein's explanation of the photoelectric effect, which introduced the idea that light can also behave as discrete packets of energy called photons. The seminar then examines the properties of these light particles, including their mass (which is incredibly small), speed, and how they interact with matter. It covers topics such as wave-particle duality, where light exhibits characteristics of both waves and particles, and delves into phenomena like interference and diffraction, which are typically associated with waves but can also be explained by the particle nature of light. The seminar also touches on modern applications of light particles in technology, from fiber optics to quantum computing, highlighting their significance in both theoretical physics and practical innovations.
