Q.
In a microscope the objective is having focal length $f_{o} = 2 cm$ and eye-piece is having focal length $f_{e} = 4 cm$ . The tube length is 32 cm. The magnification produced by this microscope for normal adjustment is __________. [2026]

Ans.
(100)

$m = \frac{l D}{f_{0} f_{e}}$

$= \frac{32}{2} \times \frac{25}{4}$

$m = 100$
