The absolute refractive index of kerosene is 1.39 .
The refractive index of kerosene at 20°C is approximately 1.448.
"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 (very high) refractive index of diamond is 2.4 at room temperature.(From Wikipedia: "Refractive index also describes the quantity that light is bent as it passes through a single substance."
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".

Yes refractive index of the material of the medium [glass] with respect to air is high for violet and low for red.
The optical density of a diamond can be found on the RI (refractive index).It is 2.417
The number is comparative. Refractive index is a dimensionless number that represents how fast radiation -- in this case, light -- travels through a medium, in this case, diamond. The number assigned to a diamond is the highest number on the scale. The scale includes gases, liquids and solids. This means that with a refractive index of 2.42, 'light travels 2.42 times as fast in vacuum as it does in a diamond'. You can read more about refractive indices, below.
I'm assuming you mean what material has the closest refractive index to diamond? Cubic Zirconia is quite close (2.2 vs. diamonds 2.42), and moissanite or silicon carbide as well (2.65).
speed of light is different for materials of different refractive index and also higher the refractive index lesser will be speed of light in that medium. so if light travels from rarer to denser medium (with respect to refractive index) then light waves will change their speed
When cut and polished , it has a high refractive index , and reflects any available light.
