Question

Is It possible to burn a paper using lens? How?​

Answer 1

Answer:

Sun's parallel rays are coming from far away which is considered infinity. So if the lens is placed in such a way that the refracted rays mark a small point on a piece of paper, it is possible to burn the paper.

Answer 2

$\huge\color{red}{Answer}$

Here is your answer-

• Yes it is possible to burn a paper with lens
• As when you place a paper in Sun and hold a lens above it, the lens will focus all the rays of the sun at a single point and if you will wait 60 to 50 seconds the paper will start burning. Due to the heat of the sun.

Hope it helps
