Q. In order to increase the angular magnification of a simple microscope, one should increase
A) The object size
B) The aperture of the lens
C) The focal length of the lens
D) The power of the lens
Explanation
(d) For least distance, the angular magnification of simple microscope is
$M = 1 + \frac{D}{f}$
$or\ M = 1 + DP$
And for normal adjustment
$M = \frac{D}{f}$
$or\ M = DP$
Hence, if the angular magnification of simple microscope increases then the power of the lens should increase.
