1.Two mirrors labelled L1for left mirror and L2 for right mirror are parallel to each other and 3.0m apart.A person standing 1.0m from the right mirror (L2) looks into this mirror and sees a series of images.The second nearest image in the right mirror is situated at a distance ------------
For the mirror L2 => OP = PI1
the image I1 will act as an object for mirror L1 and the distance of I 1 from L1 is (3+1) = 4m , hence image I2 will formed at a distance 4m , from L1 . Now I 3 will act as an object for mirror L2 and the distance of I2 from L2 = (4+3) = 7m , hence image I3 (of object I2 ) will from at a distance of 7m from mirror L2 .
