Light with a wavelength of 550 nm is incident on a single slit,
creating a diffraction pattern on a distant screen 2.5 m away. At a
point on the diffraction pattern that is 1.443 m from the central
maximum, the path length difference between the ray from the top of
the slit and the bottom of the slit results in a phase difference
of 6π radians. What is the width of the slit? (a) 1.1 µm (b) 2.2 µm
