Question
Answer the following question in detail.
What is the limitation in increasing the magnifying powers of a compound microscope?
Solution
In the case of a compound microscope,
M = `"m"_"o"xx"M"_"e"="v"_"o"/"u"_"o"xx"D"/"u"_"e"`
Thus, in order to increase mo, we need to decrease uo. Thereby, the object comes closer and closer to the focus of the objective. This increases vo and hence the length of the microscope. Therefore, mo can be increased only within the limitation of the length of the microscope.
