Expert Answer
The convex lens is a converging lens which converges the rays incident on it.
So, the rays of light from the Sun converge to a single point called the focus of the lens.
This concentrated image of the Sun burns the paper kept below the lens. Hence, the term burning glass is used for the lens.
