How is the refractive index of glass is to water is related with that of air is to water?
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".
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
Does water or air have the highest refraction index?
Actually we define refractive index with respect to a standard medium. Air has been taken as that standard. Hence refractive index of air is 1 and that of water is 1.33. But refractive index of water with respect to glass is 1.33/1.5 = 0.887 So, the answer is "water".
What best describes why the critical angle of an air-glass boundary is 39.3?
The critical angle depends on the index of refraction of the two substances, in this case, air and glass. The angle can be calculated by Snell's Law. It won't always be exactly 39.3°, since different glasses have different indices of refraction.
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.

What is the bending of light rays as it passes from one material into another?
Index Of Refraction
What has the index of refraction of 1.376?
Fill a glass with water. Put a straight rod or pencil into the water at an angle. You see an apparent bend in the straight rad. This is caused by the different indexes of refraction of air and water.
What is the index of refraction for air?
Approximately 1

The refractive index of water is 43 and for glass it is 32 with respect to airwhat is the refractive index of glass with respect to air?
"The refractive index of water is 4 / 3" means the refractive index of water with respect to air. "The refractive index of glass is 3 /2" means the refractive index of glass with respect to air. You change the question as ," what is the refractive index of glass with respect to water? The answer is it is the ratio of refractive index of of glass with respect to air to the refractive index of water with respect to air =( 3/2) divided by( 4/3) = 1.125
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).
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.
Do radio waves move faster in glass than in air?
Radio waves move faster in air. Radio waves are an example of electromagnetic radiation, just as light is. Just as materials have an index of refraction for light, they also have an index of refraction for radio waves. All electromagnetic waves have the same speed in vacuum whether they are radio, light or gamma rays. The speed of electromagnetic waves in a material is equal to the speed of light in a vacuum divided by the index of refraction for that type of wave. The index of refraction of glass for radio waves depends on the glass but is well above 1 whereas for air, it is more like 1.0001. A similar comparison can be made for visible light. The index of refraction can, of course, be measured, but for air and glass one expects them to be quite different because there is a huge difference in the densities of the two materials. Air mostly empty space between molecules and so one expects electromagnetic waves to propagate at a speed very close to the speed in empty space. As a very crude rule, one expects the long wavelength index of refraction for transparent materials to increase when the number of electrons in the medium increases. Caveat: Statements made here would have to be modified if the energy of the electromagnetic wave were near an energy where it was absorbed by the medium.
