Definition of Angular resolution
Check what you remember
Read the wording for your board, then hide it and explain Angular resolution in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Given by θ ≈ λ ÷ D in radians, and a larger D produces a smaller θ, meaning finer detail can be resolved.
