Problem
Monochromatic light of wavelength 800nm passes through a slit of width 1.2μm and forms a diffraction pattern on a distant screen. Considering only the physical limit that the sine of any angle cannot exceed 1, what is the total number of diffraction minima that can be produced?
(a) 3
(b) 2
(c) 1
(d) 4
