Ratio of the speed of light in a vacuum to the speed of light in a material?
The index of refraction.
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.
If light travels at 186000 miles per second in a perfect vacuum at what speed does sound travel under the same conditions?
Sound doesn't travel at all in a perfect vacuum. Sound needs a material substance to move anywhere.
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.
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).
does light travels three-fourths as fast through water as it does a vacuum. what is water's index in refraction?
Water's index of refraction is 1.333
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
The average speed of light is greatest in?
The velocity of light travelling through a material relates to the index of refraction of that material. In this group, air has the lowest index of refraction, follow by water, fused quartz, and crown glass. This means like travels the fastest through air, then water, then fused quarts, and finally glass.
Ratio of the speed of light in a vacuum to the speed of light in a material?
The index of refraction.
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)
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 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) .
Light travels three-fourths as fast through water as it does through a vacuum What is water's index of refraction?
1.331.33
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)
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)
Does light travel faster in a material with a higher index of refraction?
Light travels faster in liquid material with a higher index or reflection.
