(e) With D = 20 λ, use of the Pythagorean theorem leads to φ = L 1 L 2 λ = d ² + ( d + D d ² + D ² λ = 5.80 which means the rays reaching the point y = d have a phase difference of roughly 5.8 wavelengths. (f) The result of the previous part is “intermediate” – closer to 6 (constructive interference) than to 5 1 2 (destructive interference). 86. (a) The minimum path length difference occurs when both rays are nearly vertical. This would correspond to a point as far up in the picture as possible. Treating the screen
