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).
No, it does not. It the quantity being measured is less than it was in the base period, ten the index will be less than 100.No, it does not.

It is not, so the question is based on a fundamental misunderstanding.
no
Nothing is both less than 5 and greater than 10. It is impossible.
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.
No. This would imply that the speed of light in that medium was greater than the speed of light in a vacuum, which is physically impossible according to the theory of relativity. The relative index of refraction can be negative... that is, the speed in the medium may be faster than the speed in the surrounding environment... but the absolute IR cannot be negative.
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.
True ---Apex.
True
The index of refraction is a measure of how much light slows down when passing through a medium. The molecules in gases are more spread out compared to solids like glass, so there's less interaction with light, resulting in a smaller index of refraction for air compared to glass.
Each substance has an index of refraction. The index of refraction of water is about 1.3330 . The index of refraction of air at standard conditions is about 1.0003 . There is no such thing as the index of refraction of "water to air".
Eyeglasses made with high index of refraction materials are thinner than those made with standard index materials. This is because the higher refractive index allows for better light bending, which means less material is needed to achieve the same optical prescription.
A material with a high index of refraction bends light more than a material with a low index of refraction. This means that light travels slower through the material and the material appears denser to light. Materials like diamond and glass have high indexes of refraction.
Diamond has the highest index of refraction among vacuum, diamond, air, and crown glass. It has an index of refraction of around 2.42, which is higher than that of air (1.0003), vacuum (1), and crown glass (around 1.5).
Index Of Refraction
The index of refraction is a measure of how much light slows down when passing through a medium. In solids like glass, the atoms are closely packed together, causing the light to interact more with the atoms and slow down more than in air where the atoms are more spread out. This difference in atomic arrangement leads to a higher index of refraction in glass compared to air.
