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.
Formula for refractive index in terms of speed of light in vacuum and speed of light in a medium?
Refractive Index= Speed of Light in Vaccum / Speed of Light in the material
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.
The speed of light in a vacuum is 1.5 times that of the speed of light in a given material what is the index of refraction for that material?
Also 1.5. That's how the index of refraction is defined.
What is the index of refraction for a material in which light travels with a speed that is 80 percent the speed of light in a vacuum?
It's 1/0.8 = 1.25
If the speed of light in a vacuum is 1.2 times that of the speed of light in a given material what is the index of refraction for that material?
2 (no units)
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 of a material indicates how much the speed of light in the materials changes as light passes through?
The property of a material that indicates how much the speed of light changes as it passes through is called the material's refractive index. This index is a measure of how much the speed of light is reduced in a material compared to its speed in a vacuum. The higher the refractive index, the more the speed of light is reduced in that material.
The ratio of the speed of light in a medium to the speed of light in a vacuum is called its?
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 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 the property of a material that indicates how much it reduces the speed of light?
The property of a material that indicates how much it reduces the speed of light is called refractive index. Refractive index is a measure of how much light slows down when passing through a particular material compared to its speed in a vacuum.
What is a material's index of refraction?
It is the ratio between the speed of light in a vacuum, and the speed of light in the material. The angle at which light is refracted is related to the index of refraction, and can be calculated using Snell's Law.
How is the index of refraction of a substance related to the speed of light in the substance?
The index of refraction of a substance is inversely proportional to the speed of light in that substance. This means that as the index of refraction of a substance increases, the speed of light in that substance decreases.
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 the refractive index?
refractive index is the measure of how how fast or slow light travel through a material reference to the speed of light in empty space.
If the speed of a light in a vacuum is 1.5 times that of the speed of light in a given material what is the index of refraction for that material?
1.5 no units (APEX)
What equation is used to determine speed of light through material?
The equation used to determine the speed of light in a given material is v = c / n, where v is the speed of light in the material, c is the speed of light in a vacuum, and n is the refractive index of the material.
