Relació de Gladstone-Dale.
La relació de Gladstone-Dale és una llei física empírica que lliga l'índex de refracció n d'un gas amb la seva densitat. Estipula que n-1 és proporcional a la densitat ρ :
![{\displaystyle n-1={\mathcal {K))\rho }](https://wikimedia.org/api/rest_v1/media/math/render/svg/2d36ab9462f3f8c3ba03266224292760ec5dcc56)
on K és una constant[1]
en l'aproximació d'un gas perfecte, l'índex de refracció està lligat a la temperatura T i a la pressió P per
,
on K' és una constant. Sota petites variacions, es dedueix
![{\displaystyle \Delta n={\frac ((\mathcal {K))^{\prime )){T))\left(\Delta P-{\frac {P}{T))\Delta T\right)}](https://wikimedia.org/api/rest_v1/media/math/render/svg/6aabca0cc20e7222aeabc99cf711a499cd8a506d)
