Refraction index of H2O as a function of Temperature
Select the wavelength (400 nm < wavelength < 800 nm) and the Temperature range of water (0°C - 100°C). The refraction index (r) of water will be plotted as a function of the selected temperature range for the selected wavelength. A more accurate approximation by A.H. Harvey et al. (NIST, 1998) can be found here with an improved equation of state for water.
