Not only does oil immersion increase the microscopic resolution of a specimen, it is also transparent. This allows for optimal microscopy views.

How immersion oil helps in viewing an object?
This is because of the refractive propoties of the immersion oil. The oil works as a sort of secondary lens, magnifying the specimin in addition to the lens alresdy present.
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 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 objective focuses closest to the slides?
The oil immersion lens @100x
Is the low power objective lens the shortest objective lens?
scanning objective
What mirror is used for oil immersion?
100x lens is used with oil immersion
Oil immersion is used as a medium between the specimen and the oil immersion objective lens why?
Oil immersion is a technique used to increase the resolution of a microscope.

How do you remove oil from the slide and oil immerssion lens after use?
When you desire to remove oil from a slide and an immersion lens after using, for example, cedar oil, you would use Xylene to remove the oil. Natural oils can harden on the lens otherwise.
Why is 100x microscope lens called oil immersion lens?
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.
Should you store the microscope with the oil immersion lens in position?
no
Why should you never look at a wet mount slide with a oil immersion lens?
Wet mounts are not attached to the slide, it is "floating". If you use an oil immersion lens, you have to put a drop of oil on the slide cover so the light can correctly focus. The oil will cause the slide cover to stick to the end of your Oil immersion lens. When you focus the field of focus will stay the same since the slip cover is stuck to the lens. When you go to change objectives, the cover will travel with your oil immersion lense.
Which objective focuses closest to the slide when it is in focus?
The objective lens that focuses closest to the slide is 100x, it has the longest lens so the highest power. Be careful not to crack the slide and make sure you use oil if it is an oil immersion lens.
Does the microscope get stored with oil immersion lens in position over the stage?
no
What objective focuses closest to slide?
The oil immersion lens @100x
What should you do before oil immersion lens is rotated into place?
place a drop oil on the side
