Wavelength determination
What Wavelength determination means in Physics A-Level, as defined for OCR.
Definition of Wavelength determination
Check what you remember
Read the wording for your board, then hide it and explain Wavelength determination in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
The wavelength is found using the relationship λ = 2 × (node separation), measuring across several node spacings and dividing to reduce uncertainty.
