When would you need to use the oil immersion lens?
Not only does oil immersion increase the microscopic resolution of a specimen, it is also transparent. This allows for optimal microscopy views.
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.
Is paramecium protozoa or algae?
yes, paramecium is a single-celled protist. this is a seventh grade life-science standard.
What three colors would you use in an oil Protozoa painting?
You would use: Red orange yellow Blue Green Purple White Black Brown Grey Silver

Why immersion oil use in gram staining?
because immersion oil has same refractive index as like lens glass of microscope so it give clear image of object
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.
How do JCBs use hydraulics?
it runs with hydraulics .the hydraulics contains some oil immersion , fluids.
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.
Is paramecium protozoa or algae?
yes, paramecium is a single-celled protist. this is a seventh grade life-science standard.
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.
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.
Why isn't the oil immersion lens used in hanging drop procedure?
the hanging drop procedure uses a thicker slide, which could crack if the oil immersion lens is used. My bio professor worte: hanging drop slides asre too thick to use under oil.
When using the oil immersion lens if you are unable to bring the specimen into sharp focus what do you do?
use the fine focus knob until we get sharp image
