In a Frounhofer diffraction experiment, a single slit of width \(0.5 \mathrm{~mm}\) is illuminated by a monochromatic light of wavelength \(600 \mathrm{~nm}\). The diffraction pattern is observed on a screen at a distance of \(50 \mathrm{~cm}\) from the slit. What will be the linear separation of the first order minima?
(A) \(1.0 \mathrm{~nm}\)
(B) \(1.1 \mathrm{~nm}\)
(C) \(0.6 \mathrm{~mm}\)
(D) \(1.2 \mathrm{~nm}\)
