Three plane mirrors are kept as shown in the Figure A point object (O) is kept at the centroid of the triangle seen in the Figure. How many images will be formed?

A thin convex lens of focal length 'f' is put on a plane mirror as shown in the figure . When an object is kept at a distance 'a' from the lens - mirror combination , its image is formed at a distance (a)/(3) in front of the combination . The value of 'a' is :-

Two plane mirrors are kept such that angle between their reflecting surfaces is 40^(@) . A point object is kept symmetrically with respect to the mirrors. The total number of images formed by one mirror is :

Two plane mirrors intersect at origin. An object 'O' is kept at a distance R on negative y-axis as shown in the figure. The co-ordinates of images formed after three reflections will be (first reflection is is considered at m_(1) )
