Why does obtaining the image of the sun on a paper with the help of a concave mirror burn the paper?

Open in App

Solution

When sunrays fall on the concave mirror, they converge and come together in the focal plane.

Due to convergence, the intensity of sunrays increases.

Hence, image of the sun on a paper with the help of concave mirror bums the paper.
