yah! i think.....
What is standard index card measurement?
3x5 is the standard size as it closely follows the golden ratio
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)
What is the index of a cube root?
the index of a cube root is 3.
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.
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 vacuum is 1.
What is the standart refractive index of cyclohexene?
The standard refractive index of cyclohexene is approximately 1.465.
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 glass with respect to air is determined by dividing the refractive index of glass by the refractive index of air. Therefore, the refractive index of glass with respect to air would be 32/1, which equals 32.
Viva questions regarding refractive index of prism?
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?
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.
Define refractive index in terms of light?
Refractive index is a measure of how much light bends as it passes from one medium to another. It is defined as the ratio of the speed of light in a vacuum to the speed of light in the medium. A higher refractive index indicates a slower speed of light and more bending.
What medium has higher refractive index?
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.
