Slit spacing
What Slit spacing means in Physics A-Level, as defined for AQA.
Definition of Slit spacing
Check what you remember
Read the wording for your board, then hide it and explain Slit spacing in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The spacing d between adjacent slits, which with the diffraction angle θ and wavelength λ gives the grating equation.
