This angle is independent of the size of the drop, but does depend on its refractive index.

When water is employed as the medium, it greatly increases numerical aperture, since it has a refractive index of 1.44 at 193 nm, while air has an index of 1.

Aerogel is a very low density solid that can be produced with refractive index in the range from 1.002 to 1.265.

This utilises a property of and other materials specifically that a thin layer of gold on a high refractive index glass surface can absorb laser light, producing electron waves (surface plasmons) on the gold surface.

Seawater has a higher refractive index than rain water, so the radius of a rainbow in sea spray is smaller than a true rainbow.

For example, the refractive index of water is 1.33, meaning that light travels 1.33 times faster in a vacuum than it does in water.

The refractive index of the medium near the surface changes when biomolecules attach to the surface, and the SPR angle varies as a function of this change.

It works because numerical aperture is a function of the maximum angle of light that can enter the lens and the refractive index of the medium through which the light passes.

The phase velocity is the speed at which the crests of the wave move and can be faster than the speed of light in vacuum, and thereby give a refractive index below 1.

Tonga's performance on the Human Development Index and the Human Poverty Index reflects a high level of expenditure in health and education, stagnant population growth and sustained high levels of investment in the social sector.

Pure titanium dioxide has a very high index of refraction and an optical dispersion higher than diamond.

Bahrain has a high Human Development Index (ranked 48th in the world) and was recognised by the World Bank as a high income economy.

The United Nations publishes a Human Development Index (HDI) every year, which consists of the Life Expectancy Index, Education index, and Income index.

The index of maternal mortality is extremely high, and it is estimated at 1500 for 100 000 living births.

The optical class is biaxial ( ) with refractive indices Nx 1.550, Ny 1.583 and Nz 1.641.

Indeed, five of the 10 leading causes of death worldwide are related to diet and physical activity high blood pressure, high cholesterol, low intake of fruit and vegetables, high body mass index, and insufficient exercise.

Only such just growth can eventually be converted into high GNC Gross National Contentment, a truer index of economic well being.

This helps explain why the inflation rate, as measured by growth in the annual consumer price index, has remained stubbornly high.
