Question: A convex lens of crown glass ( $ n $ =1.525) will behave as a divergent lens if immersed in
[CPMT 1984]
Options:
A) Water (n =1.33)
B) In a medium of n = 1.525
C) Carbon disulphide n =1.66
D) It cannot act as a divergent lens
Show Answer
Answer:
Correct Answer: C
Solution:
A lens shows opposite behaviour if $ {\mu _{medium}}>{\mu _{lens}} $
