Momentum and diffraction
What Momentum and diffraction means in Physics A-Level, as defined for AQA.
Definition of Momentum and diffraction
Check what you remember
Read the wording for your board, then hide it and explain Momentum and diffraction in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Increasing momentum decreases λ, so the wave spreads less and the pattern becomes narrower with fringes closer together; decreasing momentum does the reverse.
