Question

The magnifying power of a compound microscope is high if

A

both eye-piece and objective have short focal lengths

B

Solution

Verified by Toppr

Correct option is C)

$Magnifying power = \frac{focal length of objective.}{focal length of eyepiece}$
So magnifing power $↑$ focal length of $↑$ objective
magnifing power $↑$ focal length of $↑$ eye piece
So option c is correct.
