Types of index numbers?
Index numbers are statistical measures that represent the relative change in a variable or a group of variables over time. The main types include price index numbers, which track changes in the price level of a basket of goods and services (e.g., Consumer Price Index), and quantity index numbers, which measure changes in the quantity of goods produced or consumed. Other types include value index numbers, which reflect changes in the total value of goods, and composite index numbers, which combine multiple indices into a single measure for broader analysis. These indices are essential for economic analysis, inflation measurement, and policy-making.
Properties of a ruby?
The chemical composition of ruby is aluminum oxide (Al 2 O3). Its specific gravity is 3.99 to 4.00 and refractive index range is 1.760-1.768 to 1.770-1.779. Ruby's hardness on Mohs scale is 9. It's the next hardest mineral after diamond.
What is the index of refraction of a material if the angle of incidence in air is 50 degrees and the angle of refraction in the material is 40 degrees?
When a ray of light passes from material 1 to material 2: N1 sin θ1 = N2 sin θ2 where N1 & N2 are the refractive indices of the materials, and θ1 is the angle of incidence, θ2 the angle of refraction. From air to the material: N1 = 1.00, θ1 = 40°, θ2 = 50°, N2 = unknown, the index of refraction of the material: → 1.00 x sin 50° = N2 x sin 40° → N2 = 1.00 x sin 50° ÷ sin 40° → N2 ≈ 1.1917 (the index of refraction of the material)
Why should the temperature of the sample be controlled during the refractive index measurement?
Controlling the temperature of the sample during refractive index measurement is important because the refractive index of a substance is sensitive to temperature changes. Fluctuations in temperature can alter the refractive index value, leading to inaccurate results. By maintaining a constant temperature, you ensure that the refractive index measurement is reliable and accurate.
What methods are commonly used for refractive index measurement in materials analysis?
Common methods for refractive index measurement in materials analysis include the Abbe refractometer, the prism spectrometer, and the interferometric technique. These methods involve measuring the bending of light as it passes through a material to determine its refractive index.
How is the refractive index measured and what methods are commonly used for this measurement?
The refractive index is measured by comparing the speed of light in a vacuum to its speed in a material. Common methods for this measurement include using a refractometer, spectrometer, or interferometer.
How do you compute the standard error in refractive index from your graph?
To compute the standard error in refractive index from a graph, calculate the standard deviation of the data points and divide it by the square root of the sample size. This will give you the standard error in your refractive index measurement.
What are the formulae of measurement?
The answer depends on what it is that you are measuring: length, temperature, condustiveity, refractive index, density?
What is the refractive index of vacuum?

The refractive index of water is 43 and for glass it is 32 with respect to airwhat is the refractive index of glass with respect to air?
"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
Viva questions regarding refractive index of prism?

How calcualate the refractive index of petrol?
The refractive index is determined experimentally.
What is refractive index of kerosene?
The absolute refractive index of kerosene is 1.39 .
What is the refractive index of diamonds?
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.
