Two mirrors, labeled LM for left mirror and RM for right mirror in the adjacent figure, are parallel to each other and 3.0 m apart. A person standing 1.0 m from the right mirror (RM) looks into this mirror and sees a series of images. How far from the person is the second closest image seen in the right mirror (RM)?

Closest image in RM is 1 m behind RM, so 2 m from the person.

Person is 2 m from LM.

His image in LM is 2 m behind LM, i.e. 5 m from RM.

Image of that in RM is 5 m behind RM: distance from person $= 5 + 1 = 6 m$ .

Second closest image is 6 m away.
