Question

Find the angular magnification produced by a simple microscope of
focal length 5cm when used not in normal adjustment.

Answer 1

As per the question,

Focal length (f)= 5cm

least distance for distinct vision (D)=25 cm

Angular magnification for simple microscope =$1+\dfrac{D}{f}$

$=1+\dfrac{25}{5}$

$=1+5$

$=6$
