Diffraction

विवर्तन

Diffraction in Class 12 Physics, under Chapter 10: Wave Optics, explains how light spreads and bends around obstacles or through narrow apertures when their size is comparable to its wavelength. Students study single-slit diffraction, the formation of a broad central maximum and weaker side maxima, and the conditions for minima. They relate the pattern’s width to wavelength, slit width, and screen distance, and distinguish diffraction from interference while interpreting diagrams and observations.
