The refractive index of Perspex, which is a brand name for a type of acrylic plastic, is around 1.49 to 1.50. This value may vary slightly depending on the specific formulation of the Perspex material.
bend towards the normal as it enters air from perspex due to the change in refractive indices. This is known as refraction and occurs whenever light passes from one medium to another with a different refractive index.
When a beam of light meets a perspex surface at an angle, it will undergo refraction, which is the bending of light as it passes from one medium to another with a different refractive index. The angle of refraction will depend on the angle of incidence and the refractive indices of the two materials.
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 absolute refractive index of kerosene is 1.39 .
The refractive index is determined experimentally.
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".
