A convex lens can burn a piece of paper using sunlight. give reason

Magnifying glasses, which are convex lenses made of glass or plastic, work by creating a magnified image of an object, so long as the distance between the object and the lens is less than the focal length of the lens. Past this distance, the lens shows a smaller, distorted image of the object. Using these principles, a magnifying glass can be used to focus the sun's rays onto a small point. The bigger the lens, the more sunlight it can focus, and the higher the magnification, the smaller the point it can focus the light into. With a little bit of practice and patience, a magnifying glass can easily burn paper or char wood.

thumb up pls

heat is easily passed or abssorbed thorough convex lenses

 A convex lens can burn a paper  using sunlight as convex lens is coverging lens it conveges the rays of sun at a particular point and as it is tranperent and can allow light to pass easily through it and when the converged rays of sunlught com to a particular point  the paper burns.

Thumbs up please
