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?

Two plane mirrros are placed as shown in the figure and a point object 'O' is placed at the orgin (a) How many images will be formed. (b) Find the positon(s) of image(s) (c) Will the incident ray passing through a pont 'P' (1,1,25) take part in image formation.

In the figure shown an object O is placed in front of a thin lens of small aperture. The dotted curves represent the extensions of the respective curves in the figure. How many images will be formed finally.

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) )

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 parallel at 20 cm from each other. A point object O is placed exactly in between them. Calculate distance between second images formed by two mirros.

The mirror images of the point (3,4,5) in the coordinate planes are A,B and C. The centroid of the triangle ABC is

For the system as shown in the figure, the image formed by the concave mirror

Two diverging lenses are kept as shown in figure. The final image formed will be

Choose the mirror image for the following figure when the mirror is kept at the MN line.
