The optical density of a medium is not the same as its physical density. The physical density of a material refers to the mass/volume ratio. Optical density determines how much a light wave is slowed down as it passes through a medium. The more optically dense a material is, the slower that a wave will move through the material.
The refractive index is a measurement of optical density. A medium with a low optical density, would have also a low refractive index.
For example air, having a low optical density has a refractive index of 1.0003, whereas water, with a higher optical density, has a higher refractive index of 1.333.

What term describes the relationship between the mass and volume of a substance?
Density describes the relationship between the mass and volume of a substance. It is calculated by dividing the mass of an object by its volume.
What is schilling density?
Schilling density is a term used in geology to refer to the thickness of a rock layer or a mineral deposit. It is typically measured in meters or feet and is important for understanding the distribution and characteristics of geological formations.
How to determine specific gravity of oils?
The term specific gravity means density in comparison to that of water. Density is weight divided by volume. So to get the volume, pour the oil into a graduated cylinder or measuring cup (same principle). To get the weight, use a scale (a chemist would use a triple beam balance). Once you have the density you can divide it by the density of water, and the result is the specific gravity.
Why does density happen?
Density occurs because the mass of particles in a substance is concentrated in a certain volume. As a result, the particles are closely packed together, leading to a measure of how much mass is contained within a given volume. Essentially, density is a measure of how compact or spread out the particles are within a substance.
What does hydryen mean?
There is no term "hydrayen" in English. It may be a misspelling or a word from another language. Can you provide more context or clarify the term?
Why does glycerin have a high refractive index?
The base line for the index of refraction is the amount of directional deviation that is produced when a beam of light travels from the air into another substance. The term "high index" is a relative term. Glycerin actually has a low index of refraction when compared to motor oil. I can't be certain but I believe that the density and opacity of a substance plays a big part in the determination of it's relative index.
What is relative index?
The ratio of speed of light in a given pair of media , gives us a measure of the extent of refraction of a ray of light as it goes from one medium to another. We use this ratio to define a term called the relative refractive index for a given pair of media . A relative refractive index is light that passes from one transparent medium to another.

What does the math term math mass mean?
mass is the density of any given object. what i mean by this is that it is how closely together the molecules are placed, aka the density.
What another term for icterus index?
The icterus index is the amount of bilirubin found in the plasma. For a fuller definition, check out the related link below.
What does general term mean?
It is an expression used in the context of sequences and refers to a way of expressing any term in the sequence using an index or counter. It is often called the nth term.
What does using a term density mean?
Term density refers to the frequency of a specific term or keyword within a body of text. It is a measure used in search engine optimization (SEO) to understand the relevance of a particular term in relation to the overall content of a webpage. By optimizing term density, you can improve the visibility and ranking of your content in search engine results.
What do you mean by the term Beta in investments?
Beta is a number that describes how the volatility of a stock varies with a nominated benchmark index. It's the covariance of the stock with respect to the index divided by the variance of the index. The related link contains more information
What is mean by term density?
Density is the ratio of an object's mass divided by its volume. The standard international unit to measure density is kilograms per cubic meter (kg/m3).
How does light rays always travel?
Light rays always travel in straight lines in a medium with a uniform refractive index. This is known as the principle of rectilinear propagation of light. However, in mediums with varying refractive indices or when interacting with surfaces, light rays can bend, reflect, or refract.
What is the medical term meaning any error in which images do not focus properly on the retina?
The medical term for this condition is "refractive error." Refractive errors occur when the shape of the eye prevents light from focusing directly on the retina, leading to blurred vision. Some common types of refractive errors include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
The term CPI stands for the words blank Index?
