When switching to the 100X lens, what should you use?
few drops of immersion oil
low light intensity
wet cloth to clean the lens for clarity
use it with a 15X eyepiece only
A 100X lens is also known as _________.
scanning lens
low power lens
high power lens
immersion oil lens
When cleaning immersion oil from a 100X lens, what should be used?
damp, soft cloth
tissue paper
dry paper towel
specialized lens paper
Calculate the following total magnification: 5X eyepiece with a 10X objective.
50X total magnification
5X total magnification
100X total magnification
15X total magnification
The __________________ lens of the microscope would show you the MOST zoomed-in image of the specimen.
low power objective
medium power objective
high power objective
scanning
usually has 4x magnifications and can be identified by a red strip band around its perimeter of the lens it is designed for getting your bearings right before moving into low power lens
high power lens
scanning lens
low power lens
oil immersion lens
usually has 10x or 20 x magnifications and can be identified by a yellow strip band around its perimeter of the lens .the objective is useful for viewing prepared specimens on slides, it will achieve somewhere around 100 to 200x for a 10x 20 x eyepiece respectively .the sort magnification is great in viewing small specimens like fly eggs, onion skin brine shrimps hair
low power lens
high pawer lens
oil immersion lens
scanning lens
it is ideal for observing the small details within a specimen sample. The total magnification for this lens is equal to 400x magnification (10x eyepiece lens x the 40x objective equals 400).identifiable by a blue strip,it is used in looking at small details like germs moulids cell
low power lens
oil immersion lens
scanning lens
high power lens
This objective lens will achieve the greatest magnification and has a total magnification of 1000x (10x eyepiece lens x the 100x objective equals 1000). However, since the refractive index of air and the glass slide are slightly different, a special oil must be used to help fill the gap between the two. Without a drop of oil, the objective lens will not work properly and you will not achieve the desired magnification and resolution.it is identifiable with a white strip on its lens
high power lens
low power lens
oil immersion
scanning lens
