Diffraction

This study guide covers wave diffraction, focusing on how waves bend when encountering obstacles or openings. It explains the relationship between diffraction and opening size, noting that smaller openings cause more pronounced diffraction. Interference patterns (bright and dark bands) resulting from wave interference are discussed, along with the concepts of constructive and destructive interference. The guide also examines single-slit diffraction setups and equations, including the small angle approximation. Finally, it explores how different opening shapes (circular, rectangular, double-slit, diffraction gratings) affect diffraction patterns.
