A ball is projected from point O on the ground. It hits a smooth vertical wall AB at a height h and rebounds elastically. The ball finally lands at a point C on the ground. During the course of motion, the maximum height attained by the ball is H. It \[\frac{OA}{OC}=\frac{1}{3},\] find the ratio \[\frac{h}{H}.\]
