What is the magnification of simple microscope having focal length 5 mm?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 51
The magnification (M) of a simple microscope is -
$M=1+\frac{D}{f}$
and,
focal length (f) = 5 mm
least distance (D) = 250 mm
$∴M=1+\frac{250}{5}=51$
