Question

name and define the kind of light beem formed by sunlight passing through convex lens?​

Answer 1

Answer:

A convex lens is also called converging lens as the parallel beam of light rays passing through it converges at a single point. This can also be shown through an experiment. Place a piece of paper on the ground during sunshine. Now hold a convex lens at some distance above the paper in such a way that a sharp image of sun is formed on the paper. This is the point where all the sunlight is concentrated and the parallel light rays of the sun get converged. In a while you will notice that the heat energy of the focussed sunlight has burned a hole in the paper where the image of sun was formed.
