Much of the area under a magnifying glass will be far colder than the area not covered by it. Only a small point or area will be hot, and much hotter at that.
This is because the light striking the glass is refracted and focused toward a point of convergence. The result is that our small place gets much hotter - as it receives all of the light concentrated - and the rest gets colder - because it isn't receiving any direct light.
What else can I help you with?
When the sun goes through a magnifying glass what is it called?
When the sun's rays pass through a magnifying glass, it is known as focusing or concentrating the sunlight. This process can create a hot spot where the light converges, resulting in increased temperature at that point.
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.
What temperature does the sun have to be when it can burn things with a magnifying glass?
The sun is always the same temperature. It is the focusing of the sunlight into a narrow spot that generates enough heat to ignite flammable materials. Even an ordinary pocket magnifying glass will do it. It is the focusing that is the trick. It concentrates all the heat that would have been spread over several sq inches, into a tiny spot - less than 1/10 inch diameter. So assume a lens diameter of 4 sq inches, and a focused spot of 1/10 a square inch, the energy concentration is 300+ times.
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!
Can you get a 3rd degree burn from the sun?
No, third-degree burns are typically caused by contact with hot liquids, flames, or chemicals. The sun can cause first and second-degree burns, but not third-degree burns, as it does not produce temperatures high enough to cause that level of burn.
Can you pop popcron by the sun?
you cant pop popcorn under direct sunlight because it doesn't get hot enough. if you put it under a magnifying glass then it might work.
When the sun goes through a magnifying glass what is it called?
When the sun's rays pass through a magnifying glass, it is known as focusing or concentrating the sunlight. This process can create a hot spot where the light converges, resulting in increased temperature at that point.
Why do ants burn under a magnifying glass?
When you place a magnifying glass over an ant and the sun is out, the light from the sun hits the convex glass and becomes concentrated at a certain point. That point will eventually become hot enough to burn the ant.
How do you cook a marsh mellow under the sun?
Take a magnifying glass and put in under the sun so that there is a small light that forms. lay the marshmellow under that light and wait.
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
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 happens if you put a magnafying glass under the sun and there's a rainbow on the ground?
If you place a magnifying glass under the sun and there is a rainbow on the ground, the focused sunlight passing through the magnifying glass could potentially start a fire on the surface beneath where it is concentrated. The rainbow itself is caused by sunlight being refracted and reflected by water droplets in the air, and would not affect the magnifying glass's ability to concentrate the sun's rays.
How do you use a magnifying glass to make toast?
put the magifying glass over sun
Is burning an ant with a magnifying glass considered as solar energy?
Yes, using a magnifying glass to burn an ant is considered utilizing solar energy. The magnifying glass focuses the Sun's rays to create heat that can burn objects, in this case, an ant.
How do you melt soap with a magnifing glass?
you can by putting a magnifying glass over the sun pointing to the soup
What is the safety rules when using a magnifying glass?
When using a microscope, you must clean the slide, but be careful with the cleaning supplies so you won't get allergies or mix chemicals with your stuff. yes i deleted that when someone posted it for the second time.
