일반물리학 2 — Diffraction: Problem 20

20 A diffraction grating illuminated by monochromatic light normal to the grating produces a certain line at angle \(\theta\). (a) What is the product of that line’s half-width and the grating’s resolving power? (b) Evaluate that product for the first order of a grating of slit separation \(850.0 \text{ nm}\) in light of wavelength \(600.0 \text{ nm}\).
