<p>Stare at graph, stare at wavelength spectrum. Figure which line belongs to which wavelength. Approximations can be a bit arbitrary, I was off by 5 nm and got 0 points for a few questions. Not my fault my brain pops 640 nm instead of 635 nm, hell, I drew a vertical line straight down from the graph.</p>
