The refractive index is 1,46-1,46 at at 20 oC.
Groundnut basically is a legume (Like pulses). But, oil can be extracted from groundnuts. So, you can call them as oil plants.
Immersion oil has a similar refractive index to glass, which helps reduce light refraction and increase resolution when viewing specimens under high magnification. By increasing the numerical aperture of the objective lens, immersion oil allows more light to be captured and produces a clearer image with improved contrast and detail.

Immersion oil is a type of oil used in microscopy to improve resolution and maximize the amount of light collected by the objective lens. It has a high refractive index, usually close to that of glass, which reduces light scattering and allows for clearer image magnification. Immersion oil is typically colorless and odorless to minimize interference with the sample being observed.
When a microscope is used with a very high magnification objective the image can be spoiled by the number of refractions as light goes from one medium to another (glass to air, for example). In order to help this a drop of special oil is placed on the slide cover slip and the bottom of the objective lens dips into the oil. The oil has the same refractive index as the glass used in cover slips and the bottom lens in the objective so there is no refraction as the light passes from glass to oil and back to glass. The objective is designed to give the best image with the oil. The refractive index of water is not the same as that of the oil, so the correction would not be right and the objective would not give the best possible image. I would also be a little wary of using water in case it damages the objective. It may be oil-proof, but that doesn't guarantee it is waterproof.this will lead to poor focusing.
The refractive index of oil varies based on its type and temperature, but it typically ranges from 1.45 to 1.55. Glycerin has a refractive index of approximately 1.47.

The refractive index of cooking oil typically ranges from 1.47 to 1.52, depending on factors such as the type of oil and temperature.
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).
The refractive index of oil can vary based on the type of oil, but typically falls in the range of 1.4 to 1.6. The refractive index of water is 1.33. Oil has a higher refractive index compared to water, which causes light to bend more when passing through oil than water.
The recommended type of immersion oil to use for microscopy is colorless, odorless, and has a refractive index closely matching that of glass, typically with a refractive index of 1.515.
Refraction is the bending of light as it passes from one medium to another. In oil, which has a higher refractive index than air, light bends more compared to water, causing a more pronounced effect. Water, with a lower refractive index, leads to less bending and a subtler refractive effect compared to oil.

When immersed in oil, glass becomes nearly invisible due to a phenomenon called "refractive index matching." This occurs because the refractive index of glass closely matches that of oil, leading to minimal light reflection or refraction at the glass-oil interface. As a result, the glass appears to disappear when submerged in oil, making it difficult to see with the naked eye.
This oil is a mixture not a compound.
