When the rays of sun are focused at point on paper using concave lens then all the rays focuses on one point of the paper and paper absorbs all the heat and starts getting heat up. Later after few seconds it starts getting burn and catches fire because of very high level of focus on one point. Concave lens helps to focus all rays at a point.
