Index of refraction sentence example
index of refraction
- Since the angles of incidence and refraction are connected by the relation sin i=µ sin r (Snell's Law), µ being the index of refraction of the medium, then the problem may be stated as follows: to determine the value of the angle i which makes D = 2 (i - r) +n (7r - 2r) a maximum or minimum, in which i and r are connected by the relation sin i =µ sin r, µ being a constant.
- 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.
- broad according to Zopf), highly refractive and colourless (or very dark, probably owing to the high index of refraction and minute size).Advertisement
- 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.Advertisement
- The crown glass used for eyeglass lenses has an index of refraction of 1.52.
- Reflection Colors: Because of the precise index of refraction of a diamond, the shadows and shades reflected within a real stone will be shades of gray.
