SUMMARY
The discussion focuses on determining the dispersion (dn/dλ) at a wavelength of 800 nm using the fitting equation y = 7e-15 x + 1.60, derived from a graph of refractive index (n) versus 1/λ². The user initially attempted to differentiate the equation but encountered inconsistencies with previous results. The correct approach involves recognizing that dn/d(1/λ²) relates to dn/dλ through the chain rule, specifically using the derivative -2/λ³. The user is encouraged to provide computed values for further assistance.
