Physics A-Level
Resolution and wavelength
What Resolution and wavelength means in Physics A-Level, as defined for AQA.
Definition of Resolution and wavelength
Check what you remember
Read the wording for your board, then hide it and explain Resolution and wavelength in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Resolution is limited by wavelength; a higher frequency shortens wavelength and improves resolution but increases attenuation in tissue, reducing penetration depth.
