The correct answer is:
Magnifying power decreases.
The magnifying power of the simple microscope is given by
$\text { M.P. }=1+\frac{D}{f}$
The focal length of red light is greater than that of blue light. Hence the magnifying power decreases.
$\text { M.P. }=1+\frac{D}{f}$
The focal length of red light is greater than that of blue light. Hence the magnifying power decreases.
