Dear Student,
In ancient times the kings use to burn the opponent ships and tents with the help of concave mirror and sunlight. Concave mirrors are converging mirror which means when parallel sun light rays fall on the surface of a concave mirror, all the sun rays after reflection converge (meet) at a single point (focus). With the help of concave mirror and parallel sun rays, kings burn the opponent ships and tents.
1. Concave mirrors are used by kings.

The mirrors are placed as such position that ships and tents are come on the focus of concave mirror and all parallel sun rays falls on the focus and burn the ship and tent.
