Unformatted text preview: 64. In the closest mirror, the “ﬁrst” image I1 is 10 cm behind the mirror and therefore 20 cm from the
object O. There are images from both O and I1 in the more distant mirror: an image I2 which is 30 cm
behind that mirror (since O is 30 cm in front of it), and an image I3 which is 50 cm behind the mirror
(since I1 is 50 cm in front of it). We note that I2 is 60 cm from O, and I3 is 80 cm from O. Returning to
the closer mirror, we ﬁnd images of I2 and I3 , as follows: an image I4 which is 70 cm behind the mirror
(since I2 is 70 cm in front of it) and an image I5 which is 90 cm behind the mirror (since I3 is 90 cm in
front of it). The distances (measured from O) for I4 and I5 are 80 cm and 100 cm, respectively. ...
