Does water or air have the highest refraction index?
Actually we define refractive index with respect to a standard medium. Air has been taken as that standard. Hence refractive index of air is 1 and that of water is 1.33. But refractive index of water with respect to glass is 1.33/1.5 = 0.887 So, the answer is "water".
What is refractive index?
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium.A simple, mathematical description of refractive index is as follows:n = velocity of light in a vacuum / velocity of light in mediumHence, the refractive index of water is 1.33, meaning that light travels 1.33 times as fast in a vacuum as it does in water.
What number indicates how optically dense a substance is?
I predict you are talking about the refractive index. the higher the value, the more dense the substance and thus light undergoes greater refraction (bending of light as it passes thru different mediums) the refractive index = sin of the angle of light made with normal in the less dense medium divide by the sin of angle in the denser medium.
How is the refractive index used?
The refractive index measures the speed of light and wavelengths. Measuring the refractive index of an object by wavelengths is very confusing to most people. Many scientists have got it figured out.
How is the refractive index of glass is to water is related with that of air is to water?
Each substance has an index of refraction. The index of refraction of water is about 1.3330 . The index of refraction of air at standard conditions is about 1.0003 . There is no such thing as the index of refraction of "water to air".
What does a refractometer do and how does it measure the refractive index of a substance?
A refractometer is a tool used to measure the refractive index of a substance, which indicates how much light is bent as it passes through the substance. The refractometer works by measuring the angle at which light is bent when passing through the substance, and then calculates the refractive index based on this angle.
What is the relationship between viscosity and refractive index?
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.
How does a refractometer work to measure the refractive index of a substance?
A refractometer works by measuring how much a substance bends light. When light passes through the substance, the refractometer calculates the angle at which the light is bent, which is used to determine the substance's refractive index.
What is the refractive index of a substance?
The refractive index of a substance is a measure of how much light bends when passing through that substance compared to the speed of light in a vacuum. It is a dimensionless quantity that determines the speed of light in that medium. The higher the refractive index, the slower light travels through the substance.
Does water or air have the highest refraction index?

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.

Does refractive index vary with the angle of incidence?
No. The refractive index is an absolute measure that determines by how much the angle of incidence is different from the angle of reflection.
What is the refractive index of a lens?
The refractive index of a lens describes how much the lens bends light as it passes through it. It quantifies how much the speed of light changes as it enters and exits the lens material. The refractive index varies depending on the type of material the lens is made of.
