Young's Double Slit Experiment | Interference Part 2 | B.Tech Physics

#YoungsDoubleSlit #InterferenceOfLight #EngineeringPhysics Young's double slit experiment explained step by step, with the reasoning behind every formula. This is Part 2 of the Interference of Light series. If you haven't seen Part 1 (coherent sources and conditions for interference), watch it first: (add Part 1 link) What you'll learn in this video: History and importance of Young's experiment Experimental setup and why a single source slit is needed How two coherent sources are formed by division of wavefront Path difference derivation (delta = yd/D) Positions of bright and dark fringes Fringe width and what it depends on Intensity distribution, I = 4 I0 cos²(φ/2) Shape of the fringes and the diffraction envelope Young's experiment in white light Effect of changing wavelength, screen distance, and slit separation Effect of immersing the setup in a liquid Effect of placing a thin sheet over one slit What happens when the source slit is moved or widened Why / why-not reasoning for each concept Who is this for? Class 12 (Physics) and B.Tech first-year students studying Engineering Physics.
