Biology A-Level
wavelength and resolution
What wavelength and resolution means in Biology A-Level, as defined for AQA.
Definition of wavelength and resolution
Check what you remember
Read the wording for your board, then hide it and explain wavelength and resolution in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The relatively long wavelength of light limits an optical microscope to a maximum resolution of about 0.2 micrometres, while electrons have a much shorter wavelength and so provide significantly higher resolution.
