Lecture
This lecture covers the interference of two coherent sources with phase shift, explaining constructive and destructive interference. It also discusses interference from multiple coherent sources, the vector sum of rotating vectors, and the conditions for maximum and minimum interference. The positions of maxima and minima are explored, along with examples for sound waves and electromagnetic waves. The lecture delves into interference with thin films, including reflection and transmission interference, and the impact of refractive indices on interference patterns.
