A diffraction grating illuminated by monochromatic light normal to the grating produces a certain line at angle

Question:

A diffraction grating illuminated by monochromatic light normal to the grating produces a certain line at angle θ.

(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 900 nm in light of wavelength 600 nm.
