A) become small, but non-zero
B) remain unchanged
C) become zero
D) become infinite
Correct Answer: D
Solution :
From lens maker's formula |
![]() |
When convex lens is dipped in a liquid of refractive index ![]() |
![]() |
or ![]() |
Dividing Eq. (i) by Eq. (ii), we get |
![]() |
But it is given that refractive index of lens is equal to refractive index of liquid i.e., ![]() |
Hence, Eq. (iii) gives, |
![]() |
