What happens to the interference pattern produced by a double-slit arrangement by doubling the slit spacing?

درار وقفہ کاری کو دوگنا کرکے ڈبل سلٹ انتظامات کے ذریعہ پیدا ہونے والے مداخلت کے نمونے کا کیا ہوتا ہے؟

Intensity increases

Fringe spacing is doubled

Fringe spacing is halves

None of these

Fringe spacing in a double-slit experiment is inversely proportional to slit spacing (Δy ∝ 1/d).

So, doubling the slit spacing results in the fringe spacing being halved.
