The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium.
A simple, mathematical description of refractive index is as follows:n = velocity of light in a vacuum / velocity of light in medium
Hence, the refractive index of water is 1.33, meaning that light travels 1.33 times as fast in a vacuum as it does in water.
Refractive index of vacuum is 1.
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
What is a prism and how does it relate to the refractive index? Explain how the refractive index of a prism affects the bending of light. How can you experimentally determine the refractive index of a prism?
The refractive index of diamonds is approximately 2.42. This high refractive index contributes to the diamond's brilliance and sparkle when light enters and exits the stone.

The refractive index is determined experimentally.
The absolute refractive index of kerosene is 1.39 .
The refractive index of diamonds is approximately 2.42. This high refractive index contributes to the diamond's brilliance and sparkle when light enters and exits the stone.
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.
To find the refractive index of groundnut oil, you can use a refractometer designed for measuring the refractive index of liquids. Place a drop of groundnut oil on the refractometer's prism and then measure the refractive index value displayed on the scale. This will give you the refractive index of groundnut oil.
It is usually expressed the other way: the ratio of the speed of light in a vacuum to the speed of light in a medium. In that case, it is called the "index of refraction".
I assume "molecular refractive index" refers to "the refractive index of a group of molecules". In this case, you just use the units for a refractive index - i.e., a dimensionless number.
is the two human body have different refractive index
