Equation (2.77) for the refractive index of water may be applied in the following range: Temperature: − 12 ≤ t (°C) ≤ 500, density 0 ≤ ρ (kg m− 3) ≤ 1060, wavelength 0.2 ≤ λ (μm) ≤ 1.1. Calculated values are also in good agreement with recent experimental results...
scale of aPapiliobutterfly (Graphium sarpedon) using Jamin–Lebedeff interference microscopy. They determined the cuticle'srefractive indexncto be 1.572, 1.552, and 1.541 at wavelengths of 400nm, 500nm, and 600nm, respectively. The slight wavelength dependence is described well byCauchy's equation...
Therefore, the refractive index (n) is inversely proportional to the wavelength and also to the speed of light. This means the greater the wavelength, the lower the refractive index. This relationship is represented by the equation: v(λ) = c/n(λ) However, for i...
The refractive index of binary tellurite glasses with various modifiers was measured down to the fifth decimal place in the wavelength range of 0.40–1.71 μm using the minimumedeviation method. An empirical equation based on the single-oscillator Drude–Voigt dispersion equation. nd2=A·Nfλ02+B...
The wavelength-dependent refractive index of a transparent optical material can often be described analytically with aSellmeier formula, which contains several empirically obtained parameters. Extended versions of such equations also describe the temperature dependence; such an equation has been used for Fig...
Researchers often provide us with data in a format ready-to-include in the refractiveindex.info dataset as soon as the data are first published. 2. Data extraction (a) Dispersion formula: When the linear refractive index as a function of wavelength is given as a dispersion formula, the ...
in ordinary glass the refractive index for violet light is about one percent greater than that for red light. A consequence of this phenomenon is that each wavelength experiences a slightly different degree of refraction when a heterogeneous light beam containing more than one frequency enters or le...
A Sellmeier formula is an equation for calculating the wavelength-dependent refractive index of a medium.
