Place the lens between sunlight and a fuel source (such as paper), adjust the lens position to be parallel to sunlight direction and adjust for the focal point where the sunlight would be concentrated to the ignition temperature of the fuel.

Why are convex lens useful?

convex lenses are for short sighted people.


What can Convex lens can produce?

A convex lens can converge a beam of parallel rays to a point on the other side of the lens. It is useful for reflecting and transmitting light.

What is a lens that is thicker in the middle than at the edges?

A lens that is thicker in the middle than at the edges is called a convex lens. This type of lens converges light rays to a focal point, making it useful in applications such as magnifying glasses and camera lenses. It causes light rays passing through it to converge towards a point.


What is a lens has a center that is thicker than its edges?

A convex lens.


What is a lens that is thinner in the center and thicker at the edges converging lens?

A lens that is thinner in the center and thicker at the edges is called a convex lens or a converging lens. It converges light rays towards a focal point, making it useful for magnifying objects and correcting farsightedness.


What kind of lens does a projector use?

projector have concave or convex


Why a convex lens is known as magnifying lens?

A convex lens is called a magnifying lens because it can converge light rays to form a magnified image of an object. This property allows objects to appear larger when viewed through the lens, making it useful for magnifying small details or text.


What lens is thick in the middle and thin at the edge?

A converging lens or a convex lens is thick in the middle and thin at the edges. It causes light rays to converge at a focal point, which makes it useful for focusing light in optical systems like cameras and telescopes.


Which lens is thicker in the center than at the edges in a microscope?

A convex lens is thicker in the center than at the edges in a microscope. This shape helps to converge light rays towards a focal point, which is useful for magnification and focusing in microscopy.


Why is a convex lens called a converging lens?

when a beam of light is passed through the convex lens it converges the beam of ligth.hence convex lens is called a converging lens.
