What Slit width and diffraction spreading means in Physics A-Level, as defined for AQA.
Definition of Slit width and diffraction spreading
Check what you remember
Read the wording for your board, then hide it and explain Slit width and diffraction spreading in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
For a given wavelength, increasing the slit width makes the central maximum narrower, so a wider slit gives a tighter pattern.
