Many materials have a well-characterized refractive index , but these indexes depend strongly upon the frequency of light. Standard refractive index measurements are taken at the "yellow doublet" sodium D line , with a wavelength of nanometers. Thus, it is especially important to cite the source for an index measurement if precision is required. Such losses become particularly significant, for example, in metals at short e. From Wikipedia, the free encyclopedia.

The dispersion diagram will plot the index of refraction of a selected glass as a function of the wavelength in microns. The scaling of both the x and y axes are user definable: The glass may be chosen from the pull down menu in the settings of this feature.

A higher value, or more 'bending power' means greater ability for the gem, with proper cutting, to re-route light back out to the observer rather than passing through the gem to the backside, and thus creating more total brilliance. A lower value means more light will 'pass through' or create a 'window' or see- through zone, as you tilt the stone or view it less than straight on. Thus, less brilliance because more light is simply escaping out the back of the gem rather than being captured and returned back out the front for you to see as light play and sparkle. The Amora Gem is the most brilliant gem of all, and a vacuuum by comparison has no brilliance which is why it is the base measure of 1.

Refraction is the change in direction of a wave due to a change in its speed , as observed when a wave passes from one medium to another. The most common example is the refraction of light , as happens in the formation of rainbows in the sky or rainbow-like bands when white light passes through a glass prism. Other types of waves also undergo refraction, for example, when sound waves pass from one medium into another.
