Convex lenses are thicker in the middle than at the edges. They cause light rays to converge. Concave lenses are thicker at the edges than they are in the middle. They cause light rays to spread out, or diverge.
a convex lens is thicker in the center then at the edges. A convex lens acts like a concave mirror, because it focuses rays of light.
A lens works by delaying light. When light rays encounter a lens, they refract the rays in the direction of the slower area, so a lens that is convex - thinker in the middle and thin on the edges - will bend all the light passing through it to come together. We design the lenses as thicker or thinner to deflect the light in the direction we want it to go.
As a thicker lens has more material to do bend the light further it it would have a shorter focal length
convex converging apex... :P
The top of the convex lens is thicker than the bottom.
They are convex lenses.
Concave lenses are thicker at the edges then at the middle. A Convex lens is a lens that is thicker in the center than at its edges.
Convex lenses are thicker in the middle than at the edges. They cause light rays to converge. Concave lenses are thicker at the edges than they are in the middle. They cause light rays to spread out, or diverge.
Convex is an adjective that describes something has a surface or boundary that curves or bulges outward. Convex lens are thicker at the center, they do cause light to converge.

A convex lens typically fits this description. Convex lenses are thinner in the middle and thicker around the edges, causing light rays passing through them to converge.

The lens concentrates the sun's rays into a tiny point of heat, which causes a match or other combustible material to ignite.
