A magnifying glass concentrates sunlight onto a small spot, which increases the intensity of the heat at that spot. When the intensity reaches a certain level, it can ignite flammable materials like paper or dry leaves, creating a fire.
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!
Yes, you can start a fire with eyeglasses by using them to focus sunlight onto tinder. Hold the glasses so that a small, concentrated beam of light is directed onto the tinder, and be patient as it may take some time to ignite. Make sure the glasses have magnifying lenses and are not made of plastic.
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.
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
A magnifying glass works by bending the light that passes through it, causing the light rays to converge and creating a larger image of the object. This magnified image is then projected onto the retina, making the object appear bigger to the observer.
To make fire using a magnifying glass, focus the sunlight through the magnifying glass onto a small pile of dry leaves, paper, or other flammable material. The concentrated sunlight will create enough heat to ignite the material and start a fire.

Yes, if you focus the rays of the sun using a magnifying glass on a small and dry surface, such as paper or leaves, it can concentrate the light and heat enough to start a fire. This is due to the magnifying glass converging the sunlight onto a small area, increasing the intensity of the heat.
no where but if you want to make fire give the black puffle an o-berri and you have fire
the magnifying glass must be positioned so as to focus the light from the sun on a single point (ex. kindling), causing heat and hopefully, a small fire

If you mean 'set fire to something' then no, there is most unlikely to be enough energy in a normal light beam even when it's focussed with a magnifying glass. It does depend on the power of the light, of course. How many watts do you think it will take
put the magifying glass over sun
there is a convex lens that magnify's what you want
Ogle her with a magnifying glass.
The refraction.
A magnifying glass is typically made with a convex lens, usually made of glass or plastic. The lens is specially shaped to magnify objects when viewed through it. The handle of the magnifying glass is usually made of plastic or metal for easy handling.
