Index of refraction Sentence Examples

The amount of separation is very small, and depends on the thickness of the glass, the index of refraction and the focal length of the telescope.

The refraction of light passing through sea-water is dependent on the salinity to the extent that the index of refraction is greater as the salinity increases.

Sarasin and longer series of experiments by Tornde and Kriimmel this relation is shown to be so close that the salinity of a sample can be ascertained by determining the index of refraction.

The line n shows the factor by which the index of refraction of the transmitted vibration is multiplied, and the curve p the intensity of the absorbed vibration for that wave-length.

The diamond has the requisite optical properties, its index of refraction being about i 6 times as large as that of ordinary glass.

The lustre is resinous to adamantine, and the index of refraction high (2.369 for sodium light).

Since the index of refraction varies with the colour or wave length of the light (see Dispersion), it follows that a system of lenses (uncorrected) projects images of different colours in somewhat different places and sizes and with different aberrations; i.e.

To be suitable for eyeglass lenses, a material must be transparent, without bubbles, and have a high index of refraction.

The crown glass used for eyeglass lenses has an index of refraction of 1.52.
