Choose the correct ray diagram of an equi convex lens which is cut as shown.

Options

A.
B.
C.
D.

Answer

B

Explanation

`(1)/(f)=(mu_("rel")-1)((1)/(R_(1))-(1)/(R_(2)))`
`rArr (1)/(f_("up"))=(mu_("rel")-1)(1)/(R)`
`(1)/(f_("low"))=(mu_("rel")-1) (2)/(R)`
`rArr (f_("lower"))/(f_("upper")) =(1)/(2)`
`rArr f_("upp")=2 f_("lower")`
Image by upper part will be at larger distance.\
