What Responsivity against wavelength means in Physics A-Level, as defined for AQA.
Definition of Responsivity against wavelength
Check what you remember
Read the wording for your board, then hide it and explain Responsivity against wavelength in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The spectral response curve plots responsivity, or photocurrent at fixed irradiance, against wavelength at fixed reverse bias.
