It actually depends on what you're trying to burn a hole through. It can from a thin piece of paper to a large block of wood.
I have only tried it for paper, and this is what I did:
You make a spot on the piece of paper where you want it to burn. Try using a black sharpie because it attracts more heat. Take a typical magnifying lens and hold it between the sun and paper. There should be a weird shape, or dash of sunlight on your mark of sunlight. Make sure the light is refracted right, and is not spread out, but more focused to one point.
It all depends on the weather or season really. During the summer, you can go outside and try it, and it will happen pretty fast. For the winter (which I tried), I was inside, in front of a mirror. I had to wait patiently for a few minutes, and the sun was moving by the hour, so I had to make sure my angle was correct.
Hope this helps :D
Roger Bacon did not invent the magnifying glass. The first recorded use of a magnifying glass was by the ancient Romans around 60 AD. Roger Bacon, a medieval philosopher and scientist, did write about the principles of magnification and lenses in the 13th century.
While the Romans did use glass extensively, there is no direct evidence to suggest they invented the magnifying glass. The earliest recorded use of a magnifying glass is attributed to the Arab scientist Alhazen in the 11th century.

A magnifying glass uses convex lenses to bend light rays so they converge at a single point, magnifying the image. This results in the image appearing larger and clearer to the eye.
there is no magnifing glass in diamond mines!
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.
With a 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.
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.
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.
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.
To create a DIY iPhone projector using a shoebox, you will need to cut a hole in one end of the shoebox to fit the magnifying glass. Place the magnifying glass in the hole at an angle. Then, place your iPhone inside the shoebox facing the magnifying glass. Turn on a video or image on your iPhone and adjust the distance between the phone and the magnifying glass until the image is in focus on a flat surface in a dark room.
It depends on the color, so i can't answer that.
If you mean to ask how a magnifying glass can use sunlight to burn a plant, then here's how.A magnifying glass focuses the light going through it so that it all converges into a single point (focal point). The light that would have otherwise been spread out over the area of the magnifying glass is "concentrated". Therefore there is much more energy hitting that one point than otherwise would be. The light raises the temperature of the plant to the point where it will burn.
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.
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.
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.
