Question:
Violet light \((\lambda=400 \mathrm{~nm})\) passing through a diffraction grating for which the slit spacing is \(6.0 \mu \mathrm{m}\) forms a pattern on a screen \(1.0 \mathrm{~m}\) away from the grating. Is the fringe located at a linear distance \(y=394 \mathrm{~mm}\) to the left of the central bright fringe a bright fringe, a dark fringe, or something in between? What is the order of this fringe?
