What kind of lens would let you focus the sun's rays to start a fire?
A convex lens, such as a magnifying glass, can focus the sun's rays onto a small point, creating enough heat to start a fire. The lens concentrates sunlight in a way that increases the temperature at the focal point, igniting flammable material.
Can a concave lens start a fire with the aid of the sun?
No, a concave lens cannot start a fire with the aid of the sun. Concave lenses cause light rays to diverge, which would spread the sunlight out rather than concentrate it to create enough heat to start a fire. For starting a fire with a lens, a convex lens or a magnifying glass is usually used to focus sunlight to a point.
What kind of lens should be used if you want to make fire with the help of lens using the rays of the sun?
You should use a convex lens to focus sunlight into a concentrated point to make fire. The curvature of the lens helps converge the sunlight, increasing its intensity at the focal point. This concentrated heat can then ignite a flammable material.
Is the human eye has a double convex or a plano convex lens?
The human eye has a double convex lens in the cornea (outermost layer) and a bi-convex lens in the crystalline lens inside the eye.
What happens when incident rays of a convex lens converge?
You mean the entering rays into the convex lens is already in convergence mode. Ok. Now as it enters into the convex lens convergence would be increased as convex lens would do only converging phenomenon.
What type of lens can start a fire?
a convex 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.
In olden days civilization in South America used a lens to start fire.what kind of lens did they use and how did the fire start?
They Used a Convex Lens

In olden days civilizations in south America use a lens to start a fire what kind of lens did they used and how did the fire start?
Well what u are refrerring to is the process of refraction. They would be using a convex lens. this lens has the ability to refract all the light rays which come from a far distance (known as infinity in physics) towards a common point (called focus). So obviously if all the rays reaching the lens from the sun are refracted by a convex lens they would heat up the point at which all of them converge. this started a fire. this can also be done with a magnifying glass as that also has a convex lens.

How can a convex lens be useful for making a fire?
A convex lens can be used to concentrate sunlight onto a small spot which can generate enough heat to start a fire. By focusing the sunlight onto a dry piece of tinder, the lens can create a hot spot that ignites the material, similar to how a magnifying glass can start a fire.
To magnify an object would you use a convex lens or a concave lens?
You would use a convex lens.
What type of lens would you use to magnify an object?
You would use a convex lens.
What kind of lens does a projector use?
projector have concave or convex
What type of lens would you use to examine a tiny insect?
convex lens
Are plano lens convex?
No - by definition. You can have a plano-convex (or -concave) lens (one side flat). Actually a purely plano "lens" would be merely a glass disc.
