Definition of Experimental uncertainty and evaluation
Check what you remember
Read the wording for your board, then hide it and explain Experimental uncertainty and evaluation in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Using several colours gives a range of frequencies and reduces the effect of random uncertainty, and the value obtained is approximate because the threshold is not perfectly sharp and the emission wavelength has a spread.
