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 temperature does paper burn in celsius?
110
How do you separate wooden marbles from glass marble?
One possible way to separate wooden marbles from glass marbles is by using a magnetic field. Since wooden marbles are typically not magnetic, while glass marbles are also not magnetic, one can use a strong magnet to attract and separate the wooden marbles from the glass marbles. The magnet will attract the wooden marbles while the glass marbles will remain unaffected and can be easily sorted out.
How many three digit numbers can you make using the digits 1 3 4 5 and 9 without repetition?
your a very unegucated chill i hope you burn in hell
How many hours or minutes can a coil burn?
It depends on the size of the coil and the burn rate.
How long does it take to burn a paper with magnifying glass?
The time it takes to burn a piece of paper with a magnifying glass depends on various factors such as the intensity of the sunlight, the distance between the magnifying glass and the paper, and the type of paper. Generally, it can take a few seconds to a couple of minutes to start a fire on the paper using a magnifying glass.
Why magnifying glass can burn paper?
A magnifying glass can burn paper by concentrating sunlight onto a small area, causing it to reach high temperatures. The lens of the magnifying glass acts as a converging lens, focusing the sunlight into a small, intense spot that can generate enough heat to ignite the paper.
Here a magnifying glass can burn a whole in paper?
A magnifying glass can focus the sunlight into a small, intense spot on the paper, causing it to heat up and eventually burn a hole. The magnifying glass acts as a lens, converging the light rays to create a high enough temperature at the focal point to ignite the paper.
What is the best material to burn with a magnifying glass?
Dry leaves or paper are good materials to burn with a magnifying glass since they ignite easily and burn quickly under focused sunlight. It is important to ensure proper safety measures are in place when conducting such experiments.
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.
Can a hot day burn wood?
With a magnifying glass

How are telescopes dangerous?
The most obvious answer to me is using them to look at the Sun. You know how a magnifying glass can be used to burn paper. Well a telescope is worse. Another one is when your leg crashes into the tripod that is holding your telescope. I have a big telescope and I did this and it hurt!
How do you burn a hole with a magnifying glass?
To burn a hole with a magnifying glass, you need to focus sunlight onto a specific spot for a prolonged period of time. Hold the magnifying glass at a specific distance and angle to concentrate the sunlight into a small, intense beam. Keep the magnifying glass steady until you see smoke or burning occurring.
How does a plant burn when a magnifying glass and the sun join?
When sunlight is focused through a magnifying glass onto a plant, the intense heat energy creates a concentrated beam of light that can raise the temperature of the plant's tissues to the point of combustion, causing it to burn. The magnifying glass acts as a lens that concentrates the sunlight onto a specific spot, increasing the temperature rapidly localized on that area.
Why do ants burn under a magnifying glass?
When a magnifying glass focuses sunlight onto an ant, it concentrates the sunlight to a small spot, increasing the intensity of the heat at that point. The intense heat causes the ant's body tissue to burn, resulting in harm or death to the ant.
Why do objects burn when light shines through a magnifying glass?
When light is concentrated through a magnifying glass, it focuses the light energy onto a small area, increasing the intensity of the light and heat generated. This can raise the temperature of the object to a point where it can catch fire or burn.
