A laser with a wavelength of 532 nm is aimed horizontally at a diffraction grating with 580 grooves per mm in a large, dark room. The grooves are oriented vertically. The laser is 2.7 m away from the diffraction grating, while a flat, white wall is 3.9 m behind the diffraction grating. Describe what appears on the wall and where.

Image a square aperture of width 149 \[Mu]m, 2775 mm away from a diffraction grating with a groove spacing of 1888 grooves/mm. You illuminate the diffraction grating by sending polychromatic light where the wavelengths are relatively close together and the average wavelength is 1037 nm through the square aperture onto the diffraction grating. What is the resolving power of the diffraction grating for second order light in this setup? (Assume the diffraction pattern is a Fraunhofer diffraction pattern.)
