Which mechanism creates destructive interference in anti-reflective lens coatings?

💡 Explanation

Destructive interference arises because the **optical path difference** creates a π phase shift between reflections from the air-coating and coating-glass interfaces; therefore, reflected waves cancel, rather than amplifying each other under constructive interference with identical phase shifts.
