because the oil have a refractive index near the glass one so we can work at high power without lossing any details by eliminating the air gap between the the specimen and the objective lens >>>> a.sh (iug)

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.
Is the low power objective lens the shortest objective lens?
scanning objective
What objective focuses closest to the slides?
The oil immersion lens @100x
What is the magnification of a high power objective?
The oil immersion lens or objective has power 90X-100X and an eyepiece lens generally in light microscope comes with 10X so total magnification of oil immersion lens is 100X10 = 1,000
What is the importance of oil in oil immersion lens of compound microscope?
In light microscopy, oil immersion is a technique used to increase the resolution of a microscope. This is achieved by immersing both the objective lens and the specimen in a transparent oil of high refractive index, thereby increasing the numerical aperture of the objective lens.

Is the low power objective lens the shortest objective lens?
scanning objective
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.
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.
What objective focuses closest to slide?
The oil immersion lens @100x
What microscope objective is best to study bacteria?
The most satisfactory way to study bacterial morphology 40x objective.
What objective focuses closest to the slides?
The oil immersion lens @100x

What objective lens provides the highest magnification?
scanning-40x low-100x high-400x
When using the oil immersion lens you should raise the objective lenses for easy application of an oil droplet to the slide is this true or false?
False
What mirror is used for oil immersion?
100x lens is used with oil immersion
