Convex Lens Concentrates The Light Energy To One Spot On The Paper So That The Heat Energy Accumulates On That One Small Spot Of Paper. As The Heat Increases, Combustion Will Occur When The Spot Becomes Too Hot & The Paper Burns.

Answer:
Concave Mirror are converging mirrors. So, when the parallel rays of sunlight fall on the surface of the mirror, they get reflected to a particular point where the paper kept. As a result, the rays produce heat energy and when the paper reaches its iginition temperature, it began to burn.
