What Wavelength separation by a grating means in Physics A-Level, as defined for OCR.
Definition of Wavelength separation by a grating
Check what you remember
Read the wording for your board, then hide it and explain Wavelength separation by a grating in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Higher orders spread out more, so the grating separates wavelengths, which is why it is used in spectrometry.
