Crystaline sugar (sucrose) has a refractive index of around 1.56. Sugar solutions can have refractive indices greater than this. Note, that the refractive index of a substance can even be determined for opaque substances. This is because the RI also determines reflective properties. So by measuring the amount of light reflected by light shining on a polished sample at a given angle, a refractive index can in principle be obtained.

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.
Does the index of refraction equal the angle of refraction?
Not exactly, the angle of refraction = the angle of incidence, which means the ratio of sine of angle of incidence to the sine of angle of refraction is constant for two media. That is sin i /sin r = constant , and this constant is called refractive index
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?
The refractive index is the ratio of the speed of light in a vacuum to the speed of light in a medium.
Ratio of the speed of light in a vacuum to the speed of light in a material?
The index of refraction.
How do you think increasing a medium's index of refraction might affect the angle of refraction?
Increasing the medium's index of refraction will cause the angle of refraction to decrease. This is because light bends more towards the normal as it enters a medium with a higher index of refraction.
How does the angle of refraction change as the index of refraction of the bottom material increases?
As the index of refraction of the bottom material increases, the angle of refraction will decrease. This relationship is governed by Snell's Law, which states that the angle of refraction is inversely proportional to the index of refraction. Therefore, higher index of refraction causes light to bend less when entering a denser medium.
How does increasing a mediums index of refraction affect the angle of refraction?
Increasing the medium's index of refraction causes the angle of refraction to decrease when light passes from a medium with a lower index of refraction to a medium with a higher index of refraction. This is due to the relationship described by Snell's Law, which governs the change in direction of a light ray as it passes from one medium to another.
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.
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.
How to calculate index refraction?
Index of refraction can be calculated using the formula n = c/v, where n is the index of refraction, c is the speed of light in a vacuum, and v is the speed of light in the medium. Just divide the speed of light in a vacuum by the speed of light in the medium to find the index of refraction for that medium.
What is the formula for the index of refraction?
The formula for calculating the index of refraction is n = c/v, where n is the index of refraction, c is the speed of light in a vacuum, and v is the speed of light in the medium.
What is the index of refraction of CR 39?
The index of refraction of CR-39 lens material is approximately 1.498.
Why index of refraction of ruby is less than the index of refraction of diamond?
The index of refraction of a material is related to the speed of light in that material. Ruby has a lower index of refraction than diamond because light travels faster through the ruby compared to diamond. This difference is due to the different arrangement of atoms and the properties of the materials.
What is the bending of light rays as it passes from one material into another?
Index Of Refraction
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.
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
