WebAbstract. e refractive index of helium for wavelengths longer than 600 Å is calculated by a variational method from the ground state representation of Hart and Herzberg. The results agree very well with the observations which refer to wavelengths between 2700 Å and 9000 Å. Export citation and abstract BibTeX RIS. WebA very high nonlinear refractive index can also result for materials with near-zero refractive index. For example, indium tin oxide (ITO) exhibits huge n 2 values in the wavelength region around 1250 nm [15]. Similar effects have been observed in aluminum-doped zinc oxide (AZO) in the 1300-nm region [16]. WebJun 1, 2004 · The refractive index of helium at atmospheric pressure can be determined from ab initio calculations in combination with careful pressure and temperature measurements.

More recently, measurements of the angle of deviation of a monochromatic beam refracted by a cryogenic liquid contained in a prism have been used. The refractive index of the cryogenic liquid …

WebThe index of refraction is always greater than or equal to 1, because c, the speed of light in vacuum, is always greater than the speed in a material. So, as you have stated, red light has a lower index of refraction than blue light since it also has a shorter wavelength, so lower index of refraction corresponds to higher speed in a material.
