What else can I help you with?
Can you burn a piece of paper using a convex lens and a bulb of 500 W?
yes, we can as we all know convex lens is a diverging lens,so,it diverges the rays of the sun .When the lens is placed over a paper,it diverges the rays,as a result of which paper burns
Can a convex lens be used to burn a piece of paper using the sunlight?
Yes, a convex lens can be used to focus sunlight onto a small spot on a piece of paper, causing it to heat up and potentially burn. By concentrating the sunlight into a small area, the lens can increase the intensity of the light and generate enough heat to ignite the paper.
How can convex lens burn a piece of paper kept under it?
A convex lens can burn a piece of paper by focusing sunlight onto a small spot on the paper, increasing the intensity of light and heat at that point. This can cause the paper to reach its ignition temperature and catch fire. The lens converges the light rays towards a focal point where the heat is concentrated, leading to burning.
How will you distinguish between a convex and concave lens using a printed piece of paper?
To distinguish between a convex and concave lens using a printed piece of paper, hold the lens against the paper with the curved side facing up. If the text appears larger and clearer through the lens, it is a convex lens. If the text appears smaller and upside down through the lens, it is a concave lens.
You need a good explanation for this question What burns faster paper wood or cardboard?
Paper burns faster as there is less mass to burn and less energy in paper, If it were wood, due to the mass of the wood it would burn Longer and brighter and less lengthened and less brighter for Cardboard.

Why magnifying lens burns a paper when hold above it for longer time?
The lense is cut in such a way( usually convex ), so that the sun's rays pass through it, then refract inwards to convirge together as a point, concentrating the heat.
Explain briefly how the sunshine duration is measured?
Sunshine duration is typically measured using a device called a sunshine recorder, which consists of a glass sphere that focuses sunlight onto a piece of paper. The recorder marks the duration of sunshine each day by burning a trace onto the paper. The length and intensity of the burn mark correspond to the amount of sunshine received.
Is water produced when paper burns?
Yes, water vapor is produced when paper burns because paper is made up of cellulose fibers, and when it burns, the cellulose breaks down into carbon dioxide and water due to the combustion process.
What is the rate at which paper burns?
5:1
What color construction paper burns fastest?
Construction paper burns at a uniform rate regardless of color because the paper composition is the same. The speed at which construction paper burns will be influenced by factors such as thickness, humidity, and air flow rather than color.

If the text appears larger and clearer through the lens, it is a convex lens. If the text appears smaller and upside down through the lens, it is a concave lens.
What kind of lens would let you focus the sun rays light to start a fire?
A magnifying lens, like a Fresnel lens or a convex lens, can concentrate sun rays to create a focal point that is intense enough to start a fire. This works by focusing sunlight onto a small area, increasing the temperature and igniting flammable material like paper or dry leaves.
What burns faster a napkin or a paper towel?
Same speed, both paper. 0,0
When paper burns what 2 materials are made?
When paper burns, it produces carbon dioxide and water vapor as the main materials.
