What happens to the image when you increase magnification?
In a light microscope when magnifiaction increases resolution decreases and the object will apear blurred. It can be removed by putting immersion oil on slides or object which increase the refractive index and cause to increase the numerical aperture which ultimately cause the better resolution as resolution power depends on numerical aperture of lens. The immersion oil used can be cedar oil.
Oil immersion is used as a medium between the specimen and the oil immersion objective lens why?
Oil immersion is used to minimize light refraction and increase resolution by eliminating the air gap between the lens and the specimen. The oil has a refractive index close to that of glass, allowing more light to enter the lens and improving the quality of the image.
What mirror is used for oil immersion?
A high-quality microscope objective lens with a specialized coating is typically used for oil immersion microscopy. The lens is designed to work with a specific type of oil (usually immersion oil) to enhance resolution and numerical aperture by reducing light loss due to refraction. Oil immersion microscopy is commonly used for high-magnification studies requiring precise imaging, such as in medical or biological research.
What objective lens provides the highest magnification?
The oil immersion objective lens provides the highest magnification in a compound light microscope, typically ranging from 90x to 100x. This lens requires a drop of oil to be placed on the slide to reduce light refraction and increase image clarity and magnification.
What is OIO in microscope?
oIO, stands for oil immersion objective. it was discovered during 1870. the OIO, magnifies the actual size of the specimen , 100 times, with the aid of placing a drop of ceddar oil at the top of the coverslip in slide. Remember that the OIO objective must touch the surface of the oil.
Why do you use on or slide to be examined with the oil immersion objective?
If you are using the oil immersion objective on a microscope, you must use oil to increase the resolution of the lens. These lens are used at very high magnification.
What is the magnification of objects observed through a 100X oil immersion objective with a 7.5X eyepiece?
The total magnification would be 750X (100X objective multiplied by 7.5X eyepiece). Oil immersion objectives are specifically designed for use with immersion oil to minimize light refraction and increase resolution when viewing specimens with high magnification.

How immersion oil helps in viewing an object?
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.
The total magnification achieved when using a 100x oil immersion lens with a 10x binocular eyepiece is?
The total magnification achieved when using a 100x oil immersion lens with a 10x binocular eyepiece is 1000x (100x objective magnification x 10x eyepiece magnification).
What would you observe if you forgot to use oil with the oil immersion lens?
Immersion oil is only required when using a light manuscript at 1000 times magnification (10x from occular lens and 100x from objective lens). At 1000x magnification the image will have poor resolution (loook fuzzy) without the use of immersion oil. This is because the cover slip on the sample and air have different refractory indexes. The light scatter that occurs during the transition from glass to air is noticable at such a high magnification. Immersion oil has a refractive index very similar to the cover slip, thus reducing the light scatter as the light passes from the sample to the objective lens.

What is the characteristics of immersion oil?
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.
What happends to field of view when you change from low power to oil immersion high power?
When changing from low power to oil immersion high power, the field of view decreases. This is because oil immersion lenses have a higher magnification power, which allows for a more detailed view of the specimen but with a narrower field of view. This increase in magnification results in a smaller area of the specimen being visible at one time.
