Optical admittance and refractive index
WebThis chapter deals with the use of methods for measuring the refractive index of optical materials. It contains five sections: The first section recalls some bases of the electromagnetic theory of light leading to the main characteristics of the index of refraction, and their consequences in geometrical optics (Snell–Descartes laws), in the spectral … WebRefractive Index. Refractive Index is the ratio of the speed of light in a vacuum to the speed of light in the specified material - a description of how light slows down as it passes through an optical material. The refractive index for optical glasses, $ \small{n_d} $, is specified at a wavelength of 587.6nm (Helium d-line).
