Question

Answer the following question in detail.

What is the limitation in increasing the magnifying powers of a compound microscope?

Answer 1

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 m_o, we need to decrease u_o. Thereby, the object comes closer and closer to the focus of the objective. This increases v_o and hence the length of the microscope. Therefore, m_o can be increased only within the limitation of the length of the microscope.
