Anti-reflective coatings increase glass transparency through destructive optical interference by utilizing thin-film interference to cancel out reflected light waves, which is a standard principle of physical optics requiring no citation.
The claim describes a textbook scientific principle of wave optics (thin-film interference and destructive interference) that governs how optical anti-reflective coatings operate. This is fundamental physics knowledge taught in introductory optics, making it common knowledge that does not require paper citations.
