Can a Magnifying Glass Burn with Light?

No no longer truly, the daylight is your ultimate guess. What the magnifying glass is doing is focusing a particular volume of the suns power right into a small area causing it to burn. keep in mind that its no longer the effortless that is burning, notwithstanding the nice and cozy temperature. regularly flashlights do not supply off a lot warmth using the indisputable fact that is amazingly power-inefficient

1. Does a magnifying glass NEED to be used to work on an Ouija board?

Its supposed to be a glass. I dont think this is worth wasting your time on. Would be better to use the glass to get drunk!

2. What's the shortcut key or setting to not have Chrome's magnifying glass from appearing by default when opening inspector

Found the answerUse CtrlShiftI (or CmdOptI on Mac) to open the DevTools.Use CtrlShiftC (or CmdShiftC on Mac) to open the DevTools in Inspect Element mode, or toggle Inspect Element mode if the DevTools are already open

3. where can I buy a magnifying glass in toronto?

Thousands of stores sell those

4. Help! A giant ant is holding a magnifying glass over me. What should I do?

Flip him the bird just before you burst into flames

5. a magnifying glass has a focal length of 10cm, at what distance from the text should you hold the glass?

This is my favorite query of the night...Pointless, however for some rationale made me snicker. Now i am laughing even more that so many people have answered this question critically!!!

6. Could you melt a mirror with a magnifying glass?

A mirror is only about 95-98% reflective. If you could concentrate enough energy so the absorbed 2-5% was enough to melt the mirror you could do it. (You would want to stand quite a way back though. When the mirror failed, the sudden scattering of all that focused energy could be dangerous.) That's one big problem with laser weapons. The high energy concentration damages the focusing mirrors and lenses.

7. Maps zoomed around specific locations (magnifying glass effect)

This document presents an algorithm to do that:Harrie, L., Sarjakoski, T., Lehto, L. A variable-scale map for small-display cartography. In: Joint International Symposium on GeoSpatial Theory, Processing and Applications (ISPRS/Commission IV, SDH2002). Ottawa, Canada, july 2002An example:EDIT: This kind of representation is quite old. See the plan Conrad Morant (1548):

8. Magnifying glass: upside down/right side up?

Its because of the convex lense, when you look at things far away it flips the image bacause of the curved design, and projects it into your eye as upside down, however when you look at something close, it looks bigger and rightside up! Hope this helps!! XD

9. How do I measure my peniis?

magnifying glass

10. Would a big magnifying glass out in space be a good weapon?

They have lots of those in space already. They can see all the way down to earth and after watching you can make you go boom. Satallites anyone? come on now.

11. how big of a magnifying glass would it take to start a fire with moonlight?

The key to this is how hot the Moon is versus how hot the Sun is. The Sun's surface temperature is about 5600K, while the Moon's surface temperature is about 360K. This means that the Sun is over 15 times as hot as the Moon, and so the light leaving its surface would carry that much more energy, all things being equal. This means that you would need 15 times the area of a lens used to start a fire with sunlight. However, you would not use a regular lens because they are inefficient and you might not be able to focus the light to a small enough spot. You would use a special type of "non-imaging" optical lens that simple concentrated the light without creating an actual image of the Moon. Then you would be able to do it. How can we prove this? Telescopes looking at other planets measured their temperatures using thermocouples (to measure heat) by focusing the light from those planets onto the thermocouples. This would raise the temperature of the thermocouple slightly, so it is possible to get heat concentrated this way, just not much of it usually.
