Once this … WebJan 17, 2024 · Apply Rayleigh's resolution criterion. Step 1: The simplest way to obtain this relationship is to use the small (diffraction) angle approximation, θ ≈ sin θ ≈ tan θ = y / D, where D is the distance from the grating to the screen and y is the distance measured on the screen. The distance between to neighbouring maxima is y m a x.
