alleryIn single-slit diffraction, the central maximum is:
ATwice as wide as the secondary maxima
BSame width as the secondary maxima
CHalf as wide as the secondary maxima
DEqual width to all other secondary maxima
Answer & Solution
Correct answer: A. Twice as wide as the secondary maxima
In single-slit diffraction, the CENTRAL MAXIMUM is TWICE AS WIDE as the secondary maxima (spans 2 × λ/a, secondary maxima span only λ/a each). Also brightest by far.
