Question
The focal length of the objective and eye lenses of a microscope are 1.6 cm and 2.5 cm. respective ly the distance between the two lenses is 21.7 cm. If the final image is formed at infinity, what is the linear magnification?
Options
A.11
B.110
C.1.1
D.44
Solution
In normal adjustment, object lies close to focus of objective and image is formed atinfinity, magnifination = 
Where f0f0 = 1.6 cm, fe = 2.5 cm, d = 21.7 cm
L = d-f0 = 21.7 - 1.6 cm, = 21.0(approx.)
⇒ m =
= 1091.1 ≈ 110
