One advantage is that it increases the resolution and clarity of the image, this is very useful for viewing specimens that would otherwise be to small to see without the oil. However it can be very messy to apply the oil and can take time and be rather difficult to clean the slide and the microscope. Moreover the slide could become damaged if vertical movement is used a lot; this is because the work distance between lens and slide is very small.

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 microscope objective is best to study bacteria?
The most satisfactory way to study bacterial morphology 40x 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.
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 would occur if water were accidentally used in place of immersion oil?
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.
What are the advantages of the low-power objective over the oil immersion objective for viewing fungi or algae?
beacause they gigady at the photoshoot

What microscope objective is best to study bacteria?
The most satisfactory way to study bacterial morphology 40x objective.
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 micrscope objective is best to study bacteria?
100x with oil immersion
What objective focuses closest to slide?
The oil immersion lens @100x
Why should the oil immersion objective be cleaned immediately after use?
Because the oil will dry and distort the refraction of the light through the 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.
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 advantage does the low-power objective have over oil immersion objective for fungi?
Live fungal cells can be observed for a long time.
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.
