Question

A convex lens of crown glass ( =1.525) will behave as a divergent lens if immersed in

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

Answer: Option C
:
C
A lens shows opposite behaviour if

μ_{m e d i u m} > μ_{l e n s}

.e., a convergent lens becomes divergent in nature
