Additional examples are adjusted to the entries in an automated way - we cannot guarantee that they are correct.
Maybe its index of refraction is a little higher, and that would be why.
Young did not use a symbol for the index of refraction, in 1807.
As the density changes, so does the index of refraction.
Any known clear substance has an index of refraction greater than 1.0.
Other factors include index of refractions for the three beams.
Typical oils used have an index of refraction around 1.515.
Glycerin has almost the same index of refraction as glass.
Red has a smaller index of refraction than blue.
The ultrasound waves create changes in the air's index of refraction.
It occurs as a mineral has 3 different indices of refraction.
The index of refraction is higher at this edge than at the other.
The core optical index of refraction is also subject to variations.
For optical applications, this is characterized by the index of refraction.
"Glass with the same index of refraction as air," he said to himself, in his own voice, though he did not do the talking.
Thomas Young was presumably the person who first used, and invented, the name "index of refraction", in 1807.
This is due to their negative index of refraction.
Higher indexes of refraction will lead to a longer wavelength frequency.
If a material's index of refraction is greater than 1, it causes light to bend inward.
Cedar oil has an index of refraction of approximately 1.516.
The term is also used to refer to lenses that provide a negative index of refraction.
The larger the index of refraction, the slower light travels in that medium.
The paper fibers have a much higher index of refraction - probably much greater than 1.5.
Changes in the index of refraction bend and bounce the light around till it almost all comes back out the front.
For X-rays, however, all materials have indices of refraction slightly below 1.
This mineral is known to have very high optical relief and has three indices of refraction.
It is a clear oil with a refractive index of 1.5168.
The refractive index of air is close to, but just greater than 1.
This is because oil has a refractive index greater than 1.
The refractive index of water at 20 C is 1.332986.
This movement will always go into the material of higher refractive index.
Water has almost the lowest refractive index you can find, 1.33.
The refractive index of the glass is the same everywhere.
It is often represented in terms of a refractive index.
In this paper he was able to show that refractive index may also be negative.
Silicon also has a very high refractive index, of about 3.5.
Water has a different refractive index than air, so the path of light changes its direction.
Every natural material so far only allows for a positive refractive index.
This ratio is called the refractive index of the material.
The refractive index is basic to the science of optics.
Measurement of small differences in the refractive index between the two data states.
Refractive indices are very high, above 2.5, which is even higher than diamond at 2.42.
What you see is an illustration of the liquid's refractive index.
This then gives rise to the variation of the refractive index.
In general, the refractive index of a glass increases with its density.
These values are similar to the refractive index of ordinary window glass, at 1.5.
The three layers are made of materials with different refractive indices.
Their refractive index, for example, may vary depending on direction.
Unfortunately, there are no solid materials with such a low refractive index.
As of 2004, the highest refractive index for a polymer was 1.76.
For comparison, ordinary window glass has a refractive index of about 1.5.
