A hollow convex lens of glass will behave like a

Text Solution

Verified by Experts

Hollow convex lens is as shown in figure
`1/f_(1)=(mu_(g)-1)(1/R_(1)-1/R_(2))=0`
(as`R_(1)=R_(2)`)
or `f_(1)=oo`, similarly `f_(2)=oo`
Therefore, a hollow equi convex lens of any material will behave like a glass plate.
