In Young’s double-slit experiment, the distance between the two identical slits is 6 . 1 times larger than the slit width. Then the number of intensity maxima observed within the central maximum of the single-slit diffraction pattern is :

Question

In Young’s double-slit experiment, the distance between the two identical slits is 6 . 1 times larger than the slit width. Then the number of intensity maxima observed within the central maximum of the single-slit diffraction pattern is :, 3, 6, 24, 12

MARKS App · Accepted Answer

d = separation between 2 slits a = slit width β y = fringe width in YDSE & β D = width of central maxima β y = λ D d = λ D 6.1 a β D = 2 λ D a β D = 2 × 6.1 β y = 12.2 β y
