Question

The magnifying power of an objective lens of a compound microscope is $8$ if the magnifying power of the compound microscope is $32$. Then calculate magnifying power of an eyepiece lens.

Answer 1

Given: Magnification of objective lens$\left(m_o\right)=8$
Magnification of compound microscope(m)$=32$
Magnification of eye lens$\left(m_e\right)=?$
Magnification of eye lens $\left(m_c\right)=\frac{m}{m_o}$
$=\frac{32}{8}=4$
Hence, magnification of eye lens$=4$.
