Q.
In order to increase the angular magnification of a simple microscope, one should increase
Ray Optics and Optical Instruments
Solution:
For least distance of distinct vision, the angular magnification of simple microscope is
$M=1+\frac{D}{f} $
$ \Rightarrow M=1+D P$
$ \left(\therefore \text{Power}(P)=\frac{1}{t}\right)$
and for normal adjustment $M=\frac{D}{f}$
$ \Rightarrow M=D P$.
Hence, if the angular magnification of simple microscope increases, then the power of the lens should increase.
