Optics Question 687
Question: A combination of two thin convex lenses of focal length 0.3 m and 0.1 m will have minimum spherical and chromatic aberrations if the distance between them is
[UPSEE 2004]
Options:
A) 0.1 m
B) 0.2 m
C) 0.3 m
D) 0.4 m
Show Answer
Answer:
Correct Answer: B
Solution:
For minimum spherical and chromatic aberration distance between lenses. $ d=f _{1}-f _{2} $
$ =0.3-0.1 $
$ =0.2m $ .
