Question

If a compound microscope $m _{1} \& m _{2}$ 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. $\frac{m_{1} m_{2}}{2}$
• D. $m_{1} m_{2}$

Answer 1

Answer: (D)

Magnification of compound microscope
$m =\frac{- V _{ o }}{ u _{ o }} \times \frac{ D }{ u _{ e }}$
$m _{1}= m _{0} \times m _{e}$
$m = m _{1} \times m _{2}$
