Determine the band pass (Δλ) that this grating could produce for green light, λ=500nm in 1st order (m=1) a grating is ruled with 500 lines/mm or d=2.0μm if the slit width is Δs=0.1mm, if the monochromatic focal length is F=200mm. Suppose the incident strike angle strikes the grating normal to its surface, θ=0.
