Answer:
When a magnifying glass is held over a piece of paper at a distance equal to its focal length, the sun's rays falling on the lens converge at a point that lies somewhere on the paper. Thus, solar energy spread over the lens' surface area gets concentrated at one point.That's when the paper starts burning.
