Optics Question 339
Question: If in compound microscope m1 and m2 be the linear magnification of the objective lens and eye lens respectively, then magnifying power of the compound microscope will be
[CPMT 1985; KCET 1994]
Options:
A) $ m _{1}-m _{2} $
B) $ \sqrt{m _{1}+m _{2}} $
C) $ (m _{1}+m _{2})/2 $
D) $ m _{1}\times m _{2} $
Show Answer
Answer:
Correct Answer: D
Solution:
Magnification of a compound microscope is given by $ m=-\frac{v _{o}}{u _{o}}\times \frac{D}{u _{e}} $
Therefore $ |m|=m _{o}\times m _{e} $ .
