How would you describe the behavior of light as it travels from the container to the air or as it travels in different media?
Light always takes the shortest path possible through any medium. As such, when it travels through a vacuum, it travels in a straight line (no refraction). When it travels through the air, the molecules in the air scatter it very slightly, causing some diffusion and refraction, depending on the composition of the air through which it passes. When it travels through water, the shortest path through that medium is not a straight, collinear line from the point of incidence...it is actually offset by a small angle (the angle of refraction). The bent path that light takes through water or another substance is actually the shortest path available to it through that 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).
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 value of index or refraction of a medium?
The index of refraction tells you by which factor the speed of light in the medium is slower than in a vacuum. This value is 1 for a vacuum, and a number greater than 1 for other media. The exact value depends on the 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
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.
What material refracts the most?
Light does not refract via a single material. Refraction occurs when light passes from one material into another of a different density. It is the amount of difference in densities that causes the refraction. The greater the difference the greater the refraction. I believe that the densest material would be diamond, so light passing through a diamond and into a vacuum would seem to be the greatest difference, causing the greatest refraction.
Suppose light travels 15 times faster in a vacuum than it does in glass What is the index of refraction for glass Express your answer as a decimal?
The index of refraction is precisely how much faster light travels in a vacuum than in the given medium. In this case, 15. Or perhaps you meant 1.5, which would be more typical for glass - answers.com sometimes eliminates some symbols from the questions.
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.
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
