Question

From as shown, find an expression for the sine of the angles at which the minimum intensity occurs in a single-slit diffraction pattern. Compare the result to as shown.

Therefore, the general condition for destructive interference is
sin Odark
m = ±1, ±2, +3,..
(37.1)
= m-
a
Analysis of the intensity variation in a diffraction pattern from a single slit of width
a shows that the intensity is given by
sin (wa sin 0/A)
(37.2)
I =I,
Ta sin 0/A
max
