Question

what are the advantages and disadvantages of viewing a specimen with a high power objective lens versus a low power objective lens?

Answer 1

Ans:- Advantages of using high power objective lens:- using high power objective lens provides the benefit of high magnification degree and thus an observer can either "zoom in" or "zoom out" the specimen in order to get details of the specimen clearly. More the magnification power of lens means more information can be collected i.e, lens with a magnification of 1000x allows us to see 1000 times its actual size.  

Disadvantages of a  high power objective lens:- When the specimen is focussed and magnified at a particular point the rest part is decreased from focus and also the observation point can turn out unfocused and blurry.

Advantages of using lower power objective lens:- The focusing of the object using this type of lens is not so difficult and also low power lenses allow scan something that may be of interest means it allows a quick scan of a large area.

Disadvantages of a low power objective lens:-The disadvantage is that it has very low magnifying power.
