It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".

What is the fixed ratio of a chemical compound called?
The fixed ratio of the elements in a chemical compound is called its RATIO OF MASSES.
What is called the Ratio between oxygen uptake and oxygen usage?
ratio between oxygen usage to oxygen uptake is called as Oxygen extraction ratio
The measure of water vapor saturation of air is called what?
The answer is actually called: The mixing ratio.
The ratio of the weight of air to the area on which it presses is called?
Atmospheric pressure
The lowest whole number ratio of the elements in a compound is called the?
An empirical formula refers to the chemical formula that indicates the simplest ratio of atoms in a compound. Two different compounds may have the same empirical formula.
What is the ratio of the speed of light in a vacuum to the speed of light in a different medium?
This is called the index of refraction. When light crosses the boundary between mediums (media) with different indices, it is bent (refracted).It's usually defined the other way around ... the ratio of the speed of light in vacuum to its speed in the medium. Since the speed of light is greater in vacuum than in any medium, the number is always greater than 1. It's referred to as the "refractive index" of the medium.
What is the index of refraction?
The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium.
What is refracting index of a medium?
Refractive index of the medium is defined as the ratio of the velocity of light in vacuum to that in the medium. No unit for refractive index.
Relationship of the speed of light in a vacuum to the speed of light in a medium where it will pass through?
Refractive index is the ratio of speeds.
What is refractive indices?
Refractive index refers to the velocity of light's ratio in a vacuum to its velocity under a specified medium.
How is the index of refraction of a substance related to the speed of light in the substance?
The substance's index of refraction isSpeed of light in vacuum / Speed of light in the substance
What of a material indicates how much the speed of light in the materials changes as light passes through?
Refractive Index: the ratio of the velocity of light in a vacuum to that in the given medium
How light propagates through a material is given by the ratio of the speed of light in vacuum to the speed of light in that material. What is this ratio called?
That is called the dielectric constant, also the square root of the relative permittivity.
What is the refractive index of a medium?
The relationship is the following: the speed of light in an object is equal to the speed of light in a vacuum, divided by the material's index of refraction. Example: A certain glass has an index of refraction of about 1.5 (it depends a bit on the type of glass!). Since the speed of light in a vacuum is 300,000 km/sec., the speed of light in such glass is (300,000 km/sec) / 1.5 = 200,000 km/sec.
Ratio of the speed of light in a vacuum to the speed of light in a material?
The index of refraction.
What is the speed of light in vacuum divided by the speed of light in medium?
The speed of light in a vacuum is 186,000 miles per second and the speed of sound at 70 degrees F at sea level is approx. 1100 feet per second. Do the math. You should come up with something around 879 thousand. (a ratio, with no units)
In what medium the speed of light will be minimum?
The speed of light is a set speed at which all electromagnetic waves travel at in a vacuum. It is 3*10^8 meters/second... That being said, when light, or any other EM wave, travels through a medium it will slow down. Every material has an index of refraction which is the ratio of the speed at which light travels in a vacuum, to the the speed it travels in that material. If you know the index of refraction, you can use Snell's law to determine the speed light will travel through a specific medium. Every medium is different, however a rule of thumb is the denser the medium, the slower light will travel through it. For example, light travels faster in the atmoshpere than it does in water.
