Figure shows an object `AB` and a plane mirror `MN` placed parallel to object. Indicate the mirror length required to see the image of object if observer's eye is at `E`.

Text Solution

Verified by Experts

Required length of mirror `= MN`

`Delta MNE & Delta A' B' E'` are similar
`(MN)/(OE) = (A' B')/(C' E) rArr MN = (A' B')/(2) = (AB)/(2)`
