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).

How is the refractive index of one medium with respect to the otherrelated to the speed of light?
The refractive index of any substance is(speed of light in vacuum)/(speed of light in that substance) .The number is greater than ' 1 ' in any material medium.
What are number greater than one called?
numbers greater than one!
How do you work out the angle of incidence and refraction?
Both can be calculated easily using Snell's Law, which you can find easily online. However to use Snell's law you will need one of the angle of incidence or refraction as well as the refractive index of the media the light ray passes through
Is one third greater than three tenths?
Yes, three tenths is greater than one third.
Is one-fourth greater than one-eight?
Yes, one-fourth is greater than one-eighth
What is the bending of light rays as it passes from one material into another?
Index Of Refraction
What is optical medium?
Optical dense refers to the index of refraction. If one medium is optically denser than another, then its index of refraction is larger, meaning the speed of light in the optically denser medium is smaller.
What is Optical denser medium?
Optical dense refers to the index of refraction. If one medium is optically denser than another, then its index of refraction is larger, meaning the speed of light in the optically denser medium is smaller.
Since light cannot travel faster than it does in a vacuum no index of refraction can ever be less than one?
True
What is the index of refraction of transparent materials?
Greater than 1.0Generally, values can be any number greater than 1.0 (which is the refractive index of a vacuum). They are generally listed as real numbers, but in fact can have an imaginary component. They can in fact also be negative, but that's only for very special materials, and not at all common. Any normal material will not have an index of refraction less than 1.
The bending of light as it moves from one material to another?
It's called refraction, and the amount of bending is determined by the index of refraction.
What property of light waves can be observed as it passes from one medium to another and change speed?
Short Answer:When light travels from one medium to another, the speed changes according to the index of refraction.Explanation:The speed of light is different in each different medium. Only in a vacuum does it reach its natural speed of 300,000 kilometers/second.We assign the speed of light in a vacuum the letter c.c=300,000 kilometers/second.Every medium which transmits light is characterized by a quantity called the index of refraction.We assign the index of refraction the letter n.n=indexof refraction.n is different for every different material and always greater than 1.The speed of light in a material is given by v=c/n.Velocity equals the speed of light in a vacuum divided by the index of refraction of the material.The speed of light in a material is always slower than in a vacuum.When light travels from one medium to another, the speed changes according to the index of refraction.
What is a measure of how much a ray light bends when it passes from one medium to another?
Index of Refraction
Does sound while passing from air to water also bend towards normal?
The law of refraction is a general result of plane waves traveling from one medium to another. Consider light. The speed of light in water is LESS than its speed in air, and it bends toward the normal (refracts). The speed of sound, however, is GREATER in water than it is in air, thus its "index of refraction" is less than one (i.e. sound bends away from the normal when traveling from air to water).
What happens if the refractive index of glass equals to the refractive index of air briefly?
When light passes from one substance to another, and both have the same refractive index, then there will be no refraction - or change of direction - at the border. It is as if there were only one substance.
Does the wavlength increase when a refraction of a wave occurs when the wave travels from one material into another?
The wavelength changes. Whether it increases or decreases depends on the index of refraction of both materials.
When light moves from one medium to another it bendshowever there is one exception to this 'rule'?
it will not bend if the two media have the same index of refraction.
