Question

Write an activity to show that how you can burn a paper using a mirror or lens but no matchstick

Answer 1

Answer:

A magnifying glass is a form of lens. A lens is a piece of glass (or similar material) which is carefully shaped so that all the light from a point on one side is focused down to a point on the other side (see the

camera obscura experiment). Light starting off from lots of different points will end up in different places forming an image.

If you are making an image of the sun the same thing happens, but because the sun is over 100 times brighter than everything else in the image and all the light from the sun hitting the lens is focused into a small spot, this spot will get very, very hot!
