Question

In the arrangement shown in figure, O is the object. An observer is to the left of convex lens and looking towards lens. The observer will see an image

A. behind the mirror
B. between lens and mirror
C. to the left of lens
D. no image will be seen

Answer 1

Correct Answer - b.
`I_(1)` is the image of O by lens. `I_(2)` is the image of `I_(1)` by mirror. Now for lens `(1)/(v)-(1)/(-4)=(1)/(10)`
`(1)/(v)-(1)/(10)-(1)/(4)rArrv=(-20)/(3)cm`
Observer will see between lens and mirror `I_(3)`.
