FM23 P12 Q29 Diffraction Grating factors | Feb/March 2023 | Cambridge 9702 A Level Physics

9702/12/F/M/23: The diagram shows a screen that is a distance L from a diffraction grating. The grating has a total number of N lines. Any two adjacent lines are a distance d apart. A beam of parallel light of
wavelength λ is incident normally on the grating. Which quantities affect the distance between the first-order diffraction maxima on the screen?
