A grating with 500 lines/mm is illuminated by λ=600 nm. What is the highest order visible? Common Error: Forgetting the condition |sinθ| ≤ 1. Unpatched solutions sometimes give m=4 (incorrect), because they use dλ = λ/mN without checking. Patched Solution: ( d = 1/500 \text mm = 2000 \text nm ). Grating equation: ( m\lambda = d \sin\theta ). ( m = \fracd\lambda = 2000/600 \approx 3.33 ), so ( m_max = 3 ). The patched PDF includes a chromatic dispersion correction and a note on blaze angle optimization for actual spectrometers.
