6. nosepiece 2. If the ocular lens on your microscope magnifhed 8x rather than the typical 10x what would be the final magnification for each objective lens? 1. Low: 2. High: 3. Oil Immersion: 3. How does the oil act upon the light so you may better visualize bacteria at 1000x magnification? 4. What is the meaning of partocal and what is the advantage of parfocal lenses? 5. Refer to Part V of your lab: 1. Before you focus a specimen with the oil immersion lens with which other lenses ün order) should you have fist resolved the specimen 2. With which lensles) are you permitted to use both coarse and fine focus? 3. With which lenses should you only use fine focus? Text Entry Copy and paste or type your submission right here Diaphragm- controls the amount of light hitting the specimen. Ocular lens- used to view the object under the lens Nosepiece-Hoids two or more objec be rotated to change the power 1 Condenser- To focus the light on the specimen

Explanation / Answer

Total magnification = objective lens x ocular lens

Considering the objective to be 10x,

Magnification = 10 x 8= 80 times magnification.. which is lesser then the typical 10x ocular .

So the answe will be 'less'.

2.:- Bending of light from one medium to another medium based on the density serves as the principle for these microscopes .. Oil is used to perform this phenomenon .. Due to the differences in the refractive index between air and the glass medium , light on the slide spreads .. but oil doesn't let this happen and the light stays at the object for most time , creating a better view for us to view 1000x bacterias .

Fine focus is used in the compound , light microscopes.
