# What happens when you put a piece of paper under a magnifying glass and expose it to the sun?

It all depends on how well you focus the beam of the magnifying glass. You need to adjust the distance from the glass to the paper until the light from the sun is concentrated in a tiny brilliant white spot. That spot is very hot as well as bright and so the paper is heated enough to start charring. It may even catch fire, so be careful to try this on a safe surface like concrete or stone paving.

Try not to look at the bright spot with unshielded eyes, as it is bright enough to damage your eyes.

dried leaves or paper

### When you place magnifying glass under the sunlight and this light absorbed by the paper what happen?

The lens of the magnifying glass concentrates the sun's light to a point. At that point the paper is heated to its ignition temperature and it can catch fire

### How do you make fire with a magnifying glass?

It's quite easy- take a magnifying glass and a dry piece of a paper ( preferably newspaper ) and go to a place where appropriate sunlight is available. Let the light of sun fall on to the magnifying glass. Bring the piece of paper beneath the magnifying glass. Now your objective is to move the magnifying glass up and down in such a way that the light emerging from the magnifying glass concentrates to a point. Hold the both things in the same position for a while, and soon you will be able to see the miracle, fire without a matchstick ! Enjoy!

### Why does a magnifying glass must be held so that the light from the sun forms a circular dot to burn paper?

A magnifying glass forms a circular dot where it focuses rays of light from the sun. The focus of a magnifying glass is at a distance from the surface of the glass itself. So a magnifying glass must be held [approximately] perpendicular to the line joining the sun and the target, and at a distance from the target which equals the focal length of the lens.

### What kind of weather instrument focuses the sun's rays onto a chart through a magnifying glass?

A sunshine recorder! A paper chart is marked with the hours. The magnifying glass is usually spherical so it and the chart don't move. When the sun shines it burns a line on the chart. The most common kind is called a Campbell-Stokes recorder. See a picture at the link below.

### How does a magnifying glass ignite a simple common fire on a simple piece of an uninked unlined computer printer paper on a piece of paper on a sunny day?

The sun emits a particle known as a photon, which carries visible light to earth. These photons contain energy, which they radiate in the form of heat. When you put a magnifying glass in the paths of these photons, the convex lense of glass narrows and focuses the photons, making them converge on a narrower point then if the lense wasn't there. This concentration of photons concentrates the heat that they emit, heating the paper up until it ignites at a certain temperature (about 451 degrees F).
