How is the index of refraction of s medium related to the speed of light inThe medium?
The index of refraction of a substance is(The speed of light in vacuum) divided by (the speed of light in the substance) .
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 does the index of refraction best describe?
Refractive index is the ratio of speed in a vacumme as to speed of light in a medium. The slowest speed of light is attain by use extremely cold sodium atom as light medium and it is succeed to slow down the speed of light from 186,000 Mile/second to 38 Mile/hr (300,000,000 m/s -> 17 m/s). This account to refractive index of 17,621,000
When light passes from a medium with a high index of refraction into a medium with a lower index of refraction which direction does the light bend?
A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.
The larger the index of refraction the light will bend as it enters?
more the incoming light will be refracted (bend) in the material.
How is the index of refraction of s medium related to the speed of light inThe medium?

How is the index of refraction of a medium related to the speed light of in the medium?
c divided by the index of refraction of the medium = the speed of light in the medium.
What describes a substance with a high index of refraction?
It causes light to slow down significantly.
How the beam would bend if the speed of light were the same in both air and water?
In that case, the ray of light would not be bent when going from one substance to another. It would be the same as if the substance remained in the same substance, for example, air. Refraction depends on the index of refraction, which is directly related to the speed of light in a substance - and not on any other physical characteristic of the substance.

When light enters a different medium the amount that the light is bent as it enters the medium is determind by the medium's index of?
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of..........=refraction
How we can calculate the velocity of light in water?
The following assumes you already know the speed of light in a vacuum. You can do measurements related to refraction, applying Snell's law to the angles you measure. This gives you the index of refraction.Once you know the index of refraction, you divide the speed of light in the vacuum by the index of refraction, to obtain the speed of light in water.
Bending of light waves when they pass through another substance?
this occurs when an object takes in light waves
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.
