Interference of Light Part 1 | Coherent Sources & Conditions | B.Tech Physics

#InterferenceOfLight #EngineeringPhysics #BTechPhysics Interference of light made clear, starting from the basics. In this video (Part 1), we build the foundation you need before Young's double slit, thin films, and Newton's rings. What you'll learn in this video: Wavefronts, rays, and Huygens' principle Principle of superposition Constructive and destructive interference Intensity formula, I max and I min, and fringe visibility Phase difference and path difference Optical path and phase change on reflection Coherent sources, and why two bulbs don't interfere Division of wavefront vs division of amplitude Conditions for sustained interference Who is this for? Class 12 (Physics) and B.Tech first-year students studying Engineering Physics.
