Quantum Physics: Light Interference

This lecture covers the phenomenon of light interference in quantum physics, focusing on concepts such as Rayleigh's criterion, wave-particle duality, and the behavior of light in different mediums. The instructor explains how interference patterns are formed, the significance of the size of a light spot, and the conditions for constructive and destructive interference. The lecture also delves into the practical applications of interference phenomena in various fields. Additionally, the lecture explores the mathematical aspects of interference, including the calculation of fringe widths and the role of phase difference in interference patterns.
