Q. If in compound microscope $m_{1}$ and $m_{2}$ be the linear magnification of the objective lens and eye lens respectively, then magnifying power of the compound microscope will be
A) $m_{1} - m_{2}$
B) $\sqrt{m_{1} + m_{2}}$
C) $(m_{1} + m_{2})/2$
D) $m_{1} \times m_{2}$
Explanation
(d) Magnification of a compound microscope is given by
$m = - \frac{v_{o}}{u_{o}} \times \frac{D}{u_{e}} \Rightarrow |m| = m_{o} \times m_{e}$
