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 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.
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.
Because that lens (it does not HAVE to be a 100x lens - other lens magnifications are also available in oil immersion constructions) is made to be in contact with a drop of special oil which covers the specimen. The oil has the same index of refraction as the front lens glass and that way a different optical construction can be used.
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.
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.
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.
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.

When using the oil immersion objective, the oil has the same refractive index as the glass. So it is like an extension of the lens. Water does not have the same refraction index as glass, so the image would not be as clear.

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.
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.
