Two spherical mirror one of convex and other concave each of same radius of curvature R are arranged coaxially at a distance 2R from each other A small circle of radius a is drawn on the convex mirror near the pole as shown in figure The radii of 3rd image taking the first reflection at the concave mirror then the successive reflection at the convex mirror and finally the third successive reflection at concave a mirror again of the circle is then value of x is 40 X M 2R
