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".
"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
The refractive index of water with respect to glass is approximately 1.33. This means that light travels about 1.33 times faster in glass compared to water.
Generally, denser mediums have higher refractive index. For example, water has a higher refractive index compared to air. Similarly, glass has a higher refractive index than water.
The refractive index of water with respect to glass is more than 1. This means that light travels faster in water than in glass, causing the light to bend when it passes from glass to water.
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".

The refractive index of glass is around 1.5, while the refractive index of water is around 1.33. This means that light travels faster in water than in glass. The difference in refractive index is why we observe light bending when it passes from air into glass or water, a phenomenon known as refraction.
The refractive index of water with respect to glass is approximately 1.33. This means that light travels about 1.33 times faster in glass compared to water.

Light will be refracted more when it goes from air to glass, as the refractive index of glass is higher than that of water. Snell's Law states that the angle of refraction is dependent on the refractive indices of the two mediums, with a higher refractive index resulting in a greater change in direction.
The refractive index of salt water depends on the concentration of salt. For typical ocean water with a salinity of around 3.5%, the refractive index is approximately 1.34. If the salinity is higher, the refractive index will also increase.
Refractive index value of a medium - when it is higher then the speed of light in that medium would become lower. In case of water it travels faster compared to that in glass. In case of diamond the speed is further reduced. Since the refractive index is inversely related to the speed of light in the medium.
Good question. This is the basis of a simple test used to identify various transparent items. In a test apparatus, one would be provided with a number of fluids each with a known and different refractive index. Thus when your sample (a headlight glass splinter for example) is put in the appropriate fluid, it will appear to disappear.
The speed of light in any medium is given by its speed of light in vacuum divided by the refractive index of the medium and so light will travel faster in water than in glass since refractive index of glass is greater than that of water.
