The one in which the speed of light is less has.
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 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.
The refractive index is inversely proportional to the wavelength, so the shorter the wavelength (the higher the frequency, or the more "blue" the light) the higher the refractive index. Conversely, the longer the wavelength (the lower the frequency, or the more "red" the light), the lower the refractive index. Therefore as wavelength of blue in less the refractive index will be maximum. For more information, follow the related link below.
Materials with a higher refractive index than their surroundings are likely to exhibit total internal reflection. Examples include diamond, glass, and water when surrounded by air. Total internal reflection occurs when light passing from a material of higher refractive index to a material of lower refractive index is reflected back into the higher refractive index material.
No, oil does not have the same refractive index as glass. Glass typically has a higher refractive index than most oils. This difference in refractive index is what causes light to bend or change direction when it passes from one medium (like oil) to another (like glass).

Refractive index of vacuum is 1.
This means that at a temperature of 25 degrees Celsius, the refractive index of water is 1.333. The refractive index is a measure of how much light bends when passing through a medium, and a higher refractive index indicates a higher bending effect.
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".
Usually a convex lens made up a material with higher refractive index would act as a converging device when kept in a medium having lower refractive index such as air. But when it is kept in a liquid as said with higher refractive index then convex lens would become as a concave lens. Now it would diverge the rays entering through it right from the liquid with higher refractive index.
The speed of light in a material with a higher refractive index is slower compared to its speed in a vacuum. This is due to the interaction of light with the atoms and molecules in the material, causing it to bend or slow down as it propagates through the medium.
Refractive Index: 1.4465
"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
