Use the principle that the image formed by a plane mirror is at the same distance behind the mirror as the object in front Therefore, the first image (I1) is formed by object P on mirror 1.
The second image ( I') (not shown on the diagram) is formed by object P on mirror 2.
The third image (I2) is formed by image (I1) on mirror 2
(Note: This image is the same as the one formed by the second image(I') on mirror 1)
