which has both theoretical and experimental data. It depends on frequency, of course, and also whether you're talking about zincblende or wurtzite GaN. For wurtzite, it also depends on direction.
If I'm reading Figure 4 correctly, the zero-frequency index of refraction is supposed to vary between about 2.25 and 2.4, depending on structure and direction.
The article is from 1996, so presumably there are newer, better papers since then.
There is no direct relationship between viscosity and refractive index. Viscosity relates to the resistance of a fluid to flow, while refractive index is a measure of how much light bends as it passes through a substance. However, the refractive index of a substance may change with temperature, which can in turn affect its viscosity.
The refractive index of hydrochloric acid varies with its concentration. For a 36% concentrated solution of hydrochloric acid, the refractive index is around 1.395 at 20°C.
The refractive index of dilute HCl depends on its concentration and temperature. Generally, for low concentrations and room temperature, the refractive index of dilute HCl is around 1.33.
The refractive index of heptane is approximately 1.387 at room temperature.
Diamond has the highest refractive index among all known substances.
Refractive index of vacuum is 1.
Refractive Index: 1.4465
"The refractive index of water is 4 / 3" means the refractive index of water with respect to air. "The refractive index of glass is 3 /2" means the refractive index of glass with respect to air. You change the question as ," what is the refractive index of glass with respect to water? The answer is it is the ratio of refractive index of of glass with respect to air to the refractive index of water with respect to air =( 3/2) divided by( 4/3) = 1.125
What is a prism and how does it relate to the refractive index? Explain how the refractive index of a prism affects the bending of light. How can you experimentally determine the refractive index of a prism?
The refractive index is determined experimentally.
The absolute refractive index of kerosene is 1.39 .
The refractive index of diamonds is approximately 2.42. This high refractive index contributes to the diamond's brilliance and sparkle when light enters and exits the stone.
Generally, denser mediums have higher refractive index. For example, water has a higher refractive index compared to air. Similarly, glass has a higher refractive index than water.
To find the refractive index of groundnut oil, you can use a refractometer designed for measuring the refractive index of liquids. Place a drop of groundnut oil on the refractometer's prism and then measure the refractive index value displayed on the scale. This will give you the refractive index of groundnut oil.
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".
I assume "molecular refractive index" refers to "the refractive index of a group of molecules". In this case, you just use the units for a refractive index - i.e., a dimensionless number.
is the two human body have different refractive index
