Question
A microscope has an objective of focal length 2 cm , eyepiece of focal length 4 cm and the tube length of 40 cm . If the distance of distinct vision of eye is 25 cm , the magnification in the microscope is
Options
A.100
B.125
C.150
D.250
Solution
$m = \frac{L}{f_{o}} \times \frac{D}{f_{e}} = \frac{40}{2} \times \frac{25}{4}$
$$\begin{matrix} & \ \\ & m = 125 \end{matrix}$$
