Also 1.5. That's how the index of refraction is defined.

Ratio of the speed of light in a vacuum to the speed of light in a material?
The index of refraction.
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
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.
When the mineral uvarovite has an index of refraction of 1.86. calculate the speed of light in this sample of uvarovite.?
Use the definition of "index of refraction". In this case, you simply need to divide the speed of light in a vacuum by the index of refraction.
Why the index of refraction is greater than to one?
It is because the index is related to the velocity of light in air (ideally vacuum) and the medium in question. Since the velocity of light in vacuum is greater than it can be in any other media, the index of refraction of these other media relative to the vacuum is greater than 1.However, if you studied light travelling through glass and then water, the index of refraction between those two would be 0.89 (approx).
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)
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)
Ratio of the speed of light in a vacuum to the speed of light in a material?
The index of refraction.
How can the index of refraction for different substances be determined mathematically?
n(index of refraction) = c(speed of light in a vacuum)/v(speed of material in the sebstance)
What is materials index of refraction?
It's (the speed of light in vacuum)/(the speed of light in the material) .
What is the materials index of refraction?
It's (the speed of light in vacuum)/(the speed of light in the material) .
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 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.
What is the bending of light rays as it passes from one material into another?
Index Of Refraction
The speed of light in a particular type of glass is 1.60 X 108 What is the index of refraction of the glass?
The index of refraction, or optical density, is the ratio of the speed of light in a vacuum to that in a given material. Therefore, the index of refraction for this glass is equal to c / v = (3.0 x 10^8 m/s) / (1.6 x 10^8 m/s) = 3.0/1.6 = 1.88
What has the highest index of refraction a vacuum a diamond air or crown glass?
A diamond has the highest index of refraction, about 2.4 Crown glass is about 1.5 and a vacuum is 1
What is the physical significance of refractive index?
The amount of refraction depends on the difference in density between two mediums. So, the amount of refraction a material has, or it's refraction index, is the amount light will bend as it goes from medium into another medium. For instance, Vacuum is considered to have a refraction index of 1 and all other materials being denser than vacuum will naturally have a larger refraction index, they bend light more. So, it simply means that- since the object has a high density it will slow down light by a greater amount.
