A double-slit experiment is performed and then redone using slits of double the previous separation. Nothing else is changed. If the approximation sin θ ≈ θ holds, what happens to the angle between the maxima?

Question

Quizplus · Accepted Answer

Doubling the slit separation in a double-slit experiment halves the angle between the maxima because the angle θ for the maxima is inversely proportional to the slit separation.
